some of the random tests have the same letter twice and yet it is supposed to be true?
Yes, it is.
Python, likely others: missing testcase for
'abcdefghijklmnopqrstuvwxyz', which is to say exactly the required characters but no additional characters. Solutions such as this one have an off-by-one bug in this caseSolved in the last attempt C++

Not a kata suggestion. See https://docs.codewars.com/training/troubleshooting#post-discourse.
thanks, my bad.
there is a problem in your test
Sorry, but, no, the problem is in your code.
Do you know what the last part means? Also, the logic in your code is wrong. Print both parts of what you're trying to compare.
easy
python tests are incorrect. when i copy the test input to my local machine the output gives expected result but copying the same code here shows wrong output. eg: "I+UG +<Twqh\tumNVfY/RbCIO[FsLVFZpx=jD" shoutld return False and it does on local machine but on codewars it shows True should equal to False.
Your solution has a bug. It works incorrectly when it is called more than once. Test it locally bu running it two times in a row, once with input "abcdefghijklmnopqrstuvw", and then with input "xyz".
It is a bug in your solution, and not a kata issue.
thanks! fixed it

Java: test will not submit. Keeps saying network error.
you can check the codewars status to see if there is downtime, but even if there is, this is not a kata issue as this is not something kata authors / contributors can fix.

because your code is not correct, try testing it with '*bcdefghijklmnopqrstuvwxyz'
which is also to say, your outside environment is lacking in test coverage
Every randomized test are incorrect for my solution. In IntelliJ all test are passed. When I copy failed random test from codewars to IntelliJ and test code, test is pass. Why?
Incorrect answer for sentence = "otkl qubh aipcgxszrv f ewm"
expected: false but was: true
This is the error message.
The input is missing several letters...
it would seem that
charCount
is holding values between tests
Ok, how to fix it? Why local test was passed, but in website not?
Its difficult to know why your code worked in your local tests without knowing your code, and without knowing your tests. Most probable reason is that you tested your code in your local tests only once, while Codewars calls your solution many times. Try to call your solution several times with different inputs and see if it still works correctly.
Python: When in vscode, it succesfully detects pangrams and non-pangrams, but when tested in here, I am stuck on the error that None value should also be True/False. Can somebody please help?
This paragraph has some information on your problem, see if it will be helpful for you.
Yes, that was what I was looking for the whole time! Thanks a lot, this was of great help :)

Approved
All tests pass in test mode but at the time of submission it fails the negative cases.
Not sure why - is anyone facing the same or have a fix?
You need to fix your solution.
Thanks for your input. Wondering how is it possible that my incorrect solution passes all tests in the test mode (both positive & negative) but not at the time of submission. Solution also works fine on Pycharm......
Check this out. Also, test your code with
is_pangram("a"). What does it return?There are only two tests in the Sample tests, and your code happens to pass the second one by chance.
Thanks for the clarifcation Chrono79. I get the issue, made some updates and submitted successfully.

Read the description again. A pangram is, by definition, a sentence containing each letter at least once, symbols don't ever matter. That code is, in fact, correct.
Oh it's really good decision, but symbols don't ever matter
Actually it does matter about symbols, given the code above.
len(set(s.lower()))will return greater than 26 if there are non-letter symbols that cause the set to be greater than 26 in length.In that code, there is nothing restricting the set to contain only letters. The user posting is pointing out that the test cases should be expanded to include non-pangrams that contain many varied symbols. So the symbols do matter for appropriate test cases to pass the kata.
Fixed in latest fork, your solution now fails.

Mednoob, thank you for your reply!
Personally, onet thing I do when I'm not provided enough context with code wars is to try it on my own machine and try to debug it from there. It really helps.
Python random tests are required. Added in this fork
Approved
Haskell:
Such solutions should not be allowed
I've published a fork that updates the random tests to generate pangrams ~50% of the time.

toLowerCasedoesn't work in place, it returns a new string, please read this: https://docs.codewars.com/training/troubleshooting/#post-discourse and mark your post as having spoiler content next time.My code in test mode works correctly with all conditions except

Why is this?

just consider what the error message is telling you:
you're trying to remove something from a list that is not in the list
I write: if there is a letter, delete it. If not, don't do anything!
You have a problem with uppercase letters.
Description should specify "contains every letter of the ENGLISH alphabet"
English is the default language of the site, so there is no need to specify it. A-Z is enough.
Same code here and on my pc returns different result on random test (Java 17). For example, i have 'false' on my PC, which is correct result, but here i have 'true', which fails the random test.
upd. it seems randomized test creates single PangramChecker instance for all test cases, so you need to clear PangramChecker state at the end of check() body.
false / truefor which test case? Random tests are... random, so saying it fails doesn't really help.Did you try to print the argument to console? An example in Python is shown here: https://docs.codewars.com/training/troubleshooting/#print-input
Is these something wrong?, C language, No 'm' or 'M' in the test string. Random_Tests should_pass_all_the_tests_provided "pzOBAiHPDQUg8EL6ilaIufonTFbYjXSFRKwkt:ZcVPsSgxG#MId"

Scala translation (with random tests!)
La funcion original chequea con el abecedario en ingles, para el español falla porque falta la ñ.
The original function checks with the English alphabet, for Spanish it fails because the ñ is missing.
Default language in the whole site is english.
Hola Chrono79 me has entendido mal, lo que quise expresar es que la funcion chequea un pangram en idioma ingles, si quisieramos chequear que el texto suministrado sea un pangram en español habria que agregar la letra ñ a la base de muestra que esta en "theMatrix" quedando para español asi
let theMatrix = 'abcdefghijklmnñopqrstuvwxyz';
Hello Chrono79, you have misunderstood me, what I wanted to express is that the function checks a pangram in English, if we wanted to check that the text supplied is a pangram in Spanish, we would have to add the letter ñ to the sample base that is in " theMatrix" left for Spanish like this
let theMatrix = 'abcdefghijklmnñopqrstuvwxyz';
Yes, but you could say the same about any other language that has its own letters, like German, Russian, etc.
Si calro a eso me refiero, por eso yo hice una variable matrix con el abecedario, para que solo cambiando eso variable la funcion sea aplicable a cualquier idioma.
Yes, of course that's what I mean, that's why I made a matrix variable with the alphabet, so that just by changing that variable the function is applicable to any language.

In this line from your code:
bool arr[26];you declare an array of a certain amount of storage, but this itself does not guarantee all elements in this array will be automatically set to zero.Your code is really hard to read without
proper code formattingHey. So I coded a function for this in C, and when entering the test cases manually in my IDE, I get the correct results. However, I'm told that they're incorrect by the editor (the same goes for the attempt tests). Not sure what to make of this. Help?
Tests / expectations of the set-up on your machine probably do not not exactly match those of the actual kata here on the site. For example, if you read the error messages, you'll see that your code fails on the first
Sample_Test, returningfalse, and yet it is a pangram.This comment has been hidden.
This comment has been hidden.
You're overwriting the function's argument. So your function always returns the same result no matter what the argument value is.
pls explain
Delete that line so your function works with whatever value is passed to it.

An
issueis reserved for when there's a provable problem with the kata, not when you can't solve the kata. Otherwise, you may post as aquestion.Step through the logic flow of your code and you will find it merely checks whether chars in the string that are alphabet letters are in fact alphabet letters, so it will always return
True.Perhaps re-read the description again carefully.

Your code is wrong, not a kata issue. Return a boolean, not a string.

It's already there.
I want to make a point, that "pangram" means a sentence using all letters from ONE language. As there are many languages using different alphabets, it's not obvious (cuz not specified in detials section) for which language we should check (english is not the only one languge in the world) or if we should detect it. For example: "The quick brown fox jumps over the lazy dog" is pangram in engilsh but it isn't in polish ¯_(ツ)_/¯.
I ignore the fact that pangram is about sentences, but details says "Ignore numbers and punctuation.", where sentence is actually a string endend with some "punctuation".
All the kata is in english, it is safe to assume the language/alphabet used is english too. It should be noted if that wasn't the case.
i can not understand it says: A pangram is a sentence that contains every single letter of the alphabet at least once. For example, the sentence "The quick brown fox jumps over the lazy dog" is a pangram. So in this sentence the letter 'h' is int the first word 'The' and in the 7th word also 'the lazy' The and the , h and e used two times why is this sentence a pangram?
At least once, means one or more times.

Hi,
The discourse pages are not there to post code. The solutions page already shows all of them.
Cheers
For those of you whose solution passes one test but not the others, I had the same issue. My problem was my solution did not reset the state of all the variables it uses each time it is run. The tests here run the solution multiple times without resetting the environment, so it passed the first time, but not subsequent times.
My code passed the example test but failed the random test even though it's giving the correct result on my system. For example, this test is meant to be false, 'Pack my box with five dozen liquor jugs.', but the random test is expecting true. Does anyone know where I might have gotten it wrong?
Why do you say it should be false? That is indeed a pangram.
Your code is not case-insensitive.
Can you pls take a look @ my code?
My solution works fine in VS Code...
Your code is not case-insensitive. So it doesn't work there either, you just didn't check it with the same input values.
Python tests are still bad since they let the following "solutions" pass:
Oh, this one, too ;-)
this one too.
Fixed in latest fork, all above solutions are invalid now.

Please use code formatting as shown here: https://docs.codewars.com/references/markdown/#code-block
Also, do read the assertion messages. They are telling you that "n" is not in the string, but your function returns
true.Lastly, do make use of
console.log()to debug your code. If you log variablelettersafter the loop, you will see it contains a space, which you shouldn't count as a letter.hi, why I got an error in my tests?? I think mine is a good solution

is your code failing all the tests?
Your solution will not work when run twice in a row.
Test Results: Fixed tests Test pangrams Test Passed Test Passed Test Passed Test Passed Test Passed Test non-pangrams Incorrect answer for 'This isn't a pangram!': True should equal False Incorrect answer for 'abcdefghijklm opqrstuvwxyz': True should equal False Incorrect answer for 'Aacdefghijklmnopqrstuvwxyz': True should equal False However whan I run this function on Pycharm the output for "Test non-pangrams" is as it should be - False
Yes, because you only run one test at once. Try running a test which expects
Trueand directly afterwards (next code line) a test which expectsFalse.Mayby I will paste here my soution and you will tell me is it right?
You dont need to paste your solution here because we know it is not right, and we know what is wrong with it. Run your solution in your PyCharm twice, like this:
and see what is the result. (edit: fixed the example)
Thanks a lot. I have visualized the codeexecution step by step and Now I have undrerstood what I have been doing wrong. Tha solution for this kata is corrected. All test passed. Tahnks once again.
one of the tests is invalid :(

None, his/her code is wrong. Use
console.log()to see what you're doing wrong.This comment has been hidden.

Because you call a function that's declared below the call, so at that point, it doesn't exist.
You're probably set to php 7.0. You can't do this in php 7.0 :
[$char, $char_capital] = int_chars($counter);, you can either change the php version to 7.4 or 8.0, or you can find another way to do this. Your code still isn't correct, but it shouldn't error out anymore.Test 3 Failed with false even though there is no ‘c’. Test 4 Failed with false even though there was no ‘p’. Test 5 Failed with false even though there was no ‘h’. And Test 6 failed with false even though there aren’t any characters. I don't get it, I though it needed to contain at least one character from the entire alphabet to have a true outcome?
Hi @Parsley Afroman - with your current message it's hard to debug; you should state:
what language (it seems like Java?)
use this Troubleshooting guide and learn to print the (unmodified) inputs you are given for each test (basically include a display-to-console command, however you do that in Java).
With point 2, you should be able to see clearly what the original input string is. Then, when you ask a question in Discourse:
Right now it's impossible to say what is what - maybe you are reading console logs incorrectly, etc
edit - some quick thoughts also: you say there is no 'p' but maybe there is a 'P' in the string? Kata asks for case insensitive - check you have implemented this?
"Cwm fjord bank glyphs vext quiz" is a pangram and my solution return true, that is, my solution its correct, but the codewars return back a error. Why?
Don't use global vars, your code fails because of that. Note your function is called several times in a row with different arguments. Make sure your function has all the things it needs to work by itself.
Thank you very much!

Closing then.
Not sure why but random tests come back as passed and example tests don't, i'm using typescript
how to upload the answer?
Error in validation Is 'abcdefghijklmopqrstuvwxyz ' a pangram? is not a pangram (n missing): expected true to equal false
It's a problem with your code:
Your code returns true for any string that has 26 or more different characters, being them alphabets, numbers or any other char.
I love it!
In Pycharm everything working good, in Solution second test is successful, but first is not. Why? I already checked docs about troubles
Maybe you didn't check the docs enough :P
Did you try to print the input to console? Which test is failing? Without this info, we can only guess.
Your approach doesn't work, it has nothing to do with Pycharm vs Codewars.
There are many cases where it will fail.
For example it returns
Truefor:"aaaaaaaaaaaaaaaaaaaaaaaaaa"It returns
Falsefor the example given in the Description of a correct pangram:"The quick brown fox jumps over the lazy dog"<- your code returnsFalsefor this.what dose the 8th test do ? i can find the mistake (

Because you're doing it the other way around, you check that every letter in the string is in the alphabet, and that'll always return true.
Oh! I see that now. Thanks for the pointer. I will try again.

Don't try to use
inputhere. The tests call your function passing it parameters and control its result. Just write a function that returns what is expected.Expected undefined to return true. What?
The log is exactly
expected undefined to equal true, which means your code should have returnedtrueand it returnedundefined(in this case it means you return nothing).COBOL translation (author is inactive).

My solution doesn't work in javascript, but does in typescript.

That's the weird thing, it failed some tests here. But testing out the same solution on JSbin worked out fine.

Read this: https://docs.codewars.com/training/troubleshooting
I did. I cannot see anything that could help. I copied test arguments from "Attempt" and pasted them into Sample Tests. So again the SAME test passes at "Test" and fails at "Attempt".
Locally in IDE it also passes.
I do not hit max call stack or something similar. I've checked already all points from the documentation.
I found the problem. It turned out argument provided by the test had trailing space which is not easy to spot. So technically it is my bad.

this kata is easy to do if you have done many kata in codewars
well gooooooooood for you
Python test is failing for s=None (should return True) with code if not s: return True, or if s is None: return True. However, just return True as the only code in the method passes the attempt. I am not sure what I am doing incorrectly. Cannot continue with testing full code until this one is passed
There is no test with None as input in Python. It is always a string, make sure you're returning instead of printing.
Thanks, misinterpreted the test result "None should equal True". I was not printing, lol

I struggled for soooo long because I forgot to consider capitalization
I attempted to use String.prototype.matchAll introduced in ES2020 in TypeScript but failed to compiled.:(
I attempted this using regex. It appears that my valid regex does not pass here. I tested my regex pattern and it works elsewhere. But, not here. Here is the pattern that causes the error: /[\s\p{P}]/gu.
No idea what you're trying to match with that regex, but it's not a kata issue. Either way, updated this kata's Node version, click reset and try again.
Even I finished book and couple of VERY simple project task was pretty cool. I found fine solutions never menthiond befor in my educational material.

And this: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/includes
And maybe use a better name for your vars,
stris an array of strings, not a string. Your code (if it worked) isn't case insensitive either.I passed all tests, but in attempt it says errors. abcd..etc is not a pangram, and another...why tests passed? and no attempt
Because sample test has less tests and attempt has more, read the error message, in Python it even tells you what the input was, so check what you're doing wrong.
yes, problem is abcdefghijklmopqrstuvwxyz is not a pangram.: True should equal False dont know why..
Very carefully look at every letter in that string.
Ah yes, missed N. But I test code with that string abcdefghijklmopqrstuvwxyz and it return false, which is correct. dont know, will keep looking.
It's happening the same to me... If I use the string "abcdefghijklmopqrstuvwxyz" as the test sample it returns False and passes the test, but not when I submit the attempt.
same here, tested on the terminal my code return false, but somehow here it return true
So basically the last test case itself is wrong and hence i can't submit my code. how did you guys submit your code ?
You can solve it by writing correct code. Nothing is broken here...

may I suggest adding a test with the sentence of characters 'a' repeated > 26 times
I did this Kata in VSC and i could compilate it without problem. The message: Response received but no data was written to STDOUT or STDERR.
Help me, please. Thanks.
Help us help you, which language? What's your code? Read this: https://docs.codewars.com/training/troubleshooting/

Please don't post solutions in Discourse.
yeah, sorry :(

Hi. If I'm not mistaken, you are using a regular expression to replace '.replace()' anything that matches /[\W\d]/g," in your string. I would recommend you search for "Regular Expressions" and solve some exercises using them to better understand them on your own. It is what I do when I want to learn more complicated or refresh my memory on regular expressions. I hope this helps you.

Not a kata suggestion, please don't post solutions in Discourse.
Tip: I would use ASCII values

Have a look at the submitted solutions and you may find some, don't you think so?
How in the world is the alphabet itself not a panagram? Are you supposed to determine whether the string is a gramatically correct sentence?
Check what you call the whole alphabet.
...Ignore this, I didn't realize there wasn't an 'n'
OP solved it, closing
is there way to solve this using Regex? I couldn't find one but love to see if someone else figured it out XD
Sure, you can, though I cannot figure out an elegant way to do it (putting all the letters in the regex to check each one is present).

Hi, read this: https://docs.codewars.com/training/troubleshooting/ and maybe start with easier katas, like 8 or 7 kyu. You shouldn't use a main method here, nor read the input from keyboard.
Thank you!!

The problem IS your code, uncomment those
print_r. Note you shouldn't useÑeither.This comment has been hidden.
What is your function returning with this string:
"The quick brown fox jumps over he lazy dog."?i made this test and i got passed but when i tried to ttend fail. And is not my code. i tested in my pc and work prefect. The problem is the formatt of last string. don't worry
In the first tests, there are actually more than one case in a single TestCase, just for you to know.
They should actually be separated into more than one TestCase but they're in the same one, so just to keep in mind if you wanted to test returning true and then false.

I don't understand, why my programm failed test, because I check my result in other sites.
Because the Codewars test suite has tests your outside setup does not have. This usually often includes more demanding tests as well as random tests.
In test ( JavaScript ): Is 'ABCD45EFGH,IJK,LMNOPQR56STUVW3XYZ' a pangram ? I receive false instead true In other sites with js compiler i got true , but here " false "

The issue marker is for when there's an issue with the Kata itself. Not when you have an issue with figuring out a solution. And certainly not when you have trouble understanding some code you found on the net.
I would suggest that you try to write a solution yourself.

Hint: does the string variable that you check in the loop contain only lowercase letters? (Answer is "No")
Also, this is not an issue with the Kata itself, so it shouldn't be marked as an issue.
yes

Changed the error messages, but your code is wrong, it's not case insensitive.

I've renamed the function, there was a typo in its name, change it to
pangramand click reset.It has both
Tandt, your code is still not case insensitive.This comment has been hidden.
The problem is when you populate
clean_strcool. I'll have alook
In a random test it expeted true but it didn't have an 'a'. Using Java.
You need to actually give the inputs, otherwise nobody will trust your comment. Especially since there are already 8000+ completions in java, so it's far more likely that you forgot something (like
(case is irrelevant)?), or you're mistaken about what the input actually is. Don't forget that sereval consecutive tests are run in the same test method, in java.So, can you give the actual failing example?
no answer...
Why is result5 a pengram but not result2 ?
Because
result2is missing a letter. Next time, mention the language too.Problem is with UTF-(8..32), or other than ascii meybe add information what to do with ąęż in my language ół is in alphabet
Please I can't submit yet the Tests say i passed all
I'm not exactly sure what I'm doing wrong but some of the random tests come back as failed even though the correct answer was provided from the code. Looking at the random test numbers, the string provided is not a pangram and my code returns false, yet it says the expected output is true. Is anyone else having this same issue?
Same problem here! If I run the same test elsewhere, it returns the correct output...
I was facing the same problem and then i realised some of the inputs contains 'prohibited characters' such as underscores, hyphens, periods, numbers, speech brackets and more! Once I removed those from the phrase, I was able to pass all the tests.

How is your code handling different letter case?
Ah thank you so much, I was thinking that wasn't the problem as The quick brown fox was working...then realised after your comment that it also has a lower case "t" that was making it work!

randomizedTests:
Test Crashed Caught unexpected signal: SIGSEGV (11). Invalid memory access.
whats wrong ?
Your solution crashes.
I pass all the 8 test cases but not the randomizedTests. Is there a special format to the randomizedTests inputs that I'm missing?
Read this please:https://github.com/codewars/codewars.com/wiki/Troubleshooting-your-solution Are you talking about Java?
Yes I'm using Java.
Try printing the input, and also read the linked article.
Thanks for the replies.
I figured out why the randomizedTests were not passing. It actually doesn't have to do anything with the inputs themselves but with how the my array variable was defined.
In the sample test cases, the Pangram object is reinstanciated every check. However in the randomizedTests part, the Pangram object isn't; only subsequent calls to the check method is done. Since my array variable is defined as a member, the array is never cleared, leaving me with the failing test. It was a simple fix, but was a bit frustrating to figure out why so to anyone having the same sort of problem as I did, be careful with how you define your variables.
Swift translation kumited :) Please review and approve
The tests should test for non-pangrams as well, as some of the presented codes return incorrect outputs if tested.

your
uniqueSortedStringis not collecting the correct values. useconsole.log()to see what's wrong. this is not a kata issue because the problem is with your code. good luck!Thanks alot. Found it!

you can make 351 easy with other characters. This solution is incorrect.

Pick a test where it fails, (
"The quick brown fox jumps over the lazy dog.") and use print (System.out.println? I do not java) to write out intermediate steps and thereby figure out where things go wrong. If it turns out that everything looks fine to you up to that huge boolean expression, then you'll want to break it up into smaller parts.Some thoughts:
A suggestion: For each character that you look at, you could print out a verdict, for example
"Found 'A', seen so far: ['A']""Encountered ' ', ignoring.""Encountered already found 'r', ignoring"Perhaps your approach wouldn't match those messages, but it's still carrying out steps that can be shown in output to allow you to observe what is being done.ok thx
This was a fun little kata. I think with the use of Regex and ES6 capabilities it makes this much easier. But what I liked about this is that it doesn't depend on more complicated math equations just foundational problem solving skills. Thanks for putting this together.
Pascal translation.
approved by someone
Python: Why import string? Is string libary not standart?
Cwm fjord bank glyphs vext quiz -- this sentence is missing x, so it should return false. However, the test cases say it should return true. What do I do?
it's not missing x. vext include x.
Alright
"The quick, brown fox jumps over the lazy dog!" there are 2 'h' chars. that is not a pangram.
A pangram is a sentence that contains all the letters of the alphabet. Duplicates are allowed.
Bruh...

The tests in Java seem to be ok:
Read this: https://github.com/codewars/codewars.com/wiki/Troubleshooting-your-solution
..
Post your code, as instructed in the link, are you saying the tests are wrong and 6223 persons passed them? Highly unlikely.
This comment has been hidden.
It's because that's not a fixed test and I can't reproduce it (after 20 submissions not even once, and seeing the code, it's impossible for it to generate a test where the expected result is wrong), stop attacking me, I'm trying to help you.
After seeing your code, it passes random tests, because they use only lowercase letters and fails some fixed test cases where there are capital letters (and those are the 4 tests you say they're wrong when they're not). Why are you using that loop for? The test suite is ok, your code is wrong.
Your solution is wrong, and you probably incorrectly deduced which test failed.
Check here how to reproduce failing test cases locally, run them in your IDE, and observe your solution failing.
Found out in Java I was failing the (8th) last test since my program for some reason couldn't handle ' . ' chars. Just having it skip that fixed it.

Yes, you can see them: https://github.com/codewars/codewars.com/wiki/Troubleshooting-your-solution#how-can-i-see-which-input-causes-my-solution-to-fail
I completed this kata with the 2 test cases given. but when I attemp it, gives me a error with 4 test cases being failed. what to do now?
Read https://github.com/codewars/codewars.com/wiki/Troubleshooting-your-solution
I understood that my logic is failing for some edge cases. Now how do I find for which it is failing? Error log doesnt give me full information
Print the input, it appears above the error log.
It's also in this paragraph of the FAQ linked above.
I have the same issue . I don't even know what are te other test cases
OP solved it, closing
This comment has been hidden.
Well, I don´t really see where the problem lies, can someone give me a hint? After 2 weeks I still don´t know whats the problem. Is there a mistake in the logic or did I forget to call something or whatever, Im still new to this page so I wouldnt know.
returns in your code are not structured correctly, and this causes a couple of problems:c++in your inner loop is never reached, because your inner loop always hitsbreakorreturnon the first iteration. Your inner loop never has a chance to execute more than once.returncan be completely missed ifsentencewould happen to be empty. Your inner loop will never enter, andreturnwon't be encountered by the control flow. Compiler does not like this, you have to have somereturnstatement which will be executed even if yourforloops won't be entered.Alright thank you, this helps me alot.
There is an error appearing saying that the code is unreachable eventhough there is nothing wrong with the code. It can´t reach the for-loop which doesn´t make any sense since the code works on a different compiler.

Given it's one of your firsts katas and
It's probably you who is doing something wrong. Don't open an issue in cases like this, use
questionlabel and provide your code using markdown formatting and marking your post as having spoiler content, otherwise there is no way to help you.Oh alright thank you
After seeing your code, it's not a kata issue, it is a problem with your code.
All my test cases work except for the last one that throws this error
abcdefghijklmopqrstuvwxyz is not a pangram.: True should equal False
so the problem is in your solution. This test case is missing 'n' so it should return False.
I tried a seperate test case just for n still doesn't work
it has a missing letter 'n'. thats why its false.
This comment has been hidden.
It's not a kata issue, it's a problem with your code, the random tests don't create a new instance of PangramChecker for each test. Read this: https://github.com/codewars/codewars.com/wiki/Troubleshooting-your-solution
Thanks for your prompt reponse. That gives me something to work with and I can now investigate further.
Problem solved - thanks for the hint :-)
My code passed all the test cases but for the last one, it is throwing a Stack trace error. Could someone please help me figure out the issue?
A problem with your code is not a kata issue, read this: https://github.com/codewars/codewars.com/wiki/Troubleshooting-your-solution about how to debug your code and if you need help, how to ask for it properly, without your code we can't know what you did wrong.
This comment has been hidden.
This message means that for some test case, your solution returned
falsewhile it should returntrue.Do you know what input makes your solution fail? If not, see here how to print function arguments, and then recreate the failing test case locally and debug through it in your IDE.
Got it. Thanks dude
can someone help me out??? I am getting failed in the last test case and i don't know to how to check for the issue...

this will fail even if there are all the alphabets in a sentence along with other characters that are not alphabets. Example: The quick brown .%^& fox jumps over the lazy dog.
So what do i do to make it work?
your solution just checks if each char is alphabetic. what you want to do instead is: find out if all 26 alphabet letters are in the input string, (so you have to keep track of them somehow)

Hey, I got this error when i attempt my code:
Caught unexpected signal: SIGSEGV (11). Invalid memory access.I can't find any error. What's problem with my code?Hard to answer if we can't see it.
Also, not a kata issue. Closing.

No language specified & duplicate issue. Closing.
Test is broken.
Hi! I'm new to this site, would appreciate any help! only failing the last 3 tests... not sure why.
Hi, read this, it'll help.
"The quick, brown fox jumps over the lazy dog!" is not paragram! Where is "h", "k","t" ??? its False
There.
i am so stupid sorry
Happens to the best of us!
just making sure, I can use two for loops one to iterate the letters the other to iterate the senstce right ?
