it uses different version of C language which would be different than what i use, i use C17 and somehow it isnt available here
This challenge works with every version of C language. You are approaching it incorrectly, not in a way how Codewars challenges should be solved. See if this article helps.
my issue is bc i'm french haha i wrote "nombre" instead of "number" in english.
First time in codeWars !
my issue were the wording Even instead of even, same for Odd instead of odd.
This is a great exercise for those who want to start with confidence! If you read this, keep practicing, programming is funny!
Thanks
was fun! on my first attempt, i tried to make nested functions for odd + even, but ended up realising i could just nuke it xD. hope we all have nice coding journeys!
Hello world
GTYBC
Simple challenge for beginner coder. We will only get better from here guys ;)

This paragraph should answer your questions.

Bugged kata, -21 and -977 are not even.
And who says they are? Can you explain what the problem is exactly?
Your solution causes following error:
Your solution incorrectly returns
"Even"for n=-21.Bugged user.
how to do the test any coding. whatever i type it shows error
Found it in the below comments
Hardest Kata ever (in BF)
very nice problem!
Ugh, I thought it would be more difficult. If you are stuck, catch my support!
Hi everyone, there is a problem with table Numbers. Even simple query 'select * from Numbers' returns error
You don't have to create a new table. You are supposed to write a
SELECTquery. I will clarify this in the solution setup.Ok, but why on SQlite simple query doesn't returns an error and on PostgreSQL returns?
Because these two behave very differently. Most of the challenges are intended to be run with Postgres.
Thanks, I passed!
Maybe mb but I didn't read the solution setup, as it was written awkwardly. No intent updating the Details?
I have the solution, but the test, say it's wrong :/, who can help me ?
This comment has been hidden.
yes also saw and i changed again. so now the name of the function is evenOrOdd.
and the error:
ReferenceError: even_or_odd is not defined at /home/codewarrior/index.js:12:10 at /home/codewarrior/index.js:16:5 at Object.handleError
so i think this task is not difficult but i got some error :)
But your current code passes all tests. Did you modify sample tests for this error to happen?
No, i never touch the original test :/
Either copy your code and hit Reset button at the bottom, or simply click Attempt. I don't see how it wouldn't work, I ran it myself and it passed.
now working :) after the reset! thx :)
It's too easy
It's supposed to be easy
This comment has been hidden.
It's not
2 == 0, there is something else before it. You should try following some tutorial to get familiar with fundamentals of the language before solving katas.The index starts at 0. I used the modulo % to add 2 to the power of 0. This = 2 and also = Even. no need for anything else as the remander and only have aone result. That is = 1 and is Odd.
I suck at explaining and doing math so my appoligies in advanced for the crude explanation. However that is how I got passed this Kata. I also tried to explain without giving the whole thing away.
thank you very much i understand now.
i will leave this here: the "" is where you write your code not some 'string' thing, i got very confused tbh.

wrong the first time because of identity. OH MY GOD

N0pE. It has been solved by over 140K coders in your language alone.
you are trying to print the input
instead you need to return a value
Thanks! I tried just returning the string , and it worked. I guess i am used to printing strings not returning them.

You were alreay asked to not post solutions in kata discourses. Please don't do this.
sorry, its my first time in the website and idk how to post the solution in the solutions section, anyway wont do it again mb
You do not need to post your code to the "Solutions" section, it appears there after you click the "Submit" button after passing tests. Your solution for this kata is here (grouped with a thousand of other users). You can see it by using the "View: Mine" filter on the solutions page.
In this type of challenges, when the solution is relatively simple, I enjoy devising a response that intentionally complicates the situation.
Just a simple question to test us beginners :fire
how to submit solution?

Hello everyone, who finds it difficult to solve the problem, don’t worry, don’t rush, we are all learning here and what seems difficult at first will become simple over time. Just find out how to determine whether a number is even or not. And then simply based on this number, return the string ("Even" or "Odd")
thanks mane u really helped my morale here
This comment has been hidden.
Your code is very close to being correct!
The name of the column alias should be given without 'single quotes', it should be
AS is_even.would have been easier if i knew i wasn't allowed to use print and expected to use return instead xD
It's somewhat implied by the "Create a function that [...] returns ...".
Also it's kind of documented.
well i didn't really read that, so much as just started playing around with the challenges :') but i got there in the end, just thought i'd leave a comment in case someone did the same thing as me xD
Thanks so much!!! I thought this challlenge was relatively easy, but it would throw up errors every time until I saw your comment!! Lifesaver!

Your solution is already present in the solutions tab for all to see and discuss. Sharing it under discourse - unformatted, no less - is redundant. Even if you mark it as spoiler, it will still spoil it for those who solved the Kata in other languages but not JavaScript yet.

On Codewars, you don't work with input/output. You instead have to write functions that return values.
Here's an overview of how it works: https://docs.codewars.com/training/training-example
Thank you so much B1ts - that's really helpful and appreciate the lightning response!
The problem was a good one for begginers to boost their confidence. One can solve this just by checking the rightmost bit of the number : if the bit is 0, the number is even else odd.
that breaks however if you submit 2, instead of 2.0

Good job, thanks P.s.: doesn't work

You shouldn't add anything to the table, you only need to execute a select statement.
As Chrono79 wrote, don't add anything or alter the given table. In SELECT statement, you can define a new column in you output and wrote a constant or formula to populate that column. Use this.
very nice problem!

Your function should return the result instead of printing it. Please mark your post as having spoiler content next time.
im writing it in c++, it gives error for int main() dk why tho, anyone can help?
Try asking on Discord. You need to write a function that returns a value, not use
cinorcout.First of all, you have missed the main keyword. Also the if-else syntax is wrong.One more thing, you need to return one of the strings "Even" or "Odd", not print it.I would suggest you to first learn the basic syntax of the language, then try solving the problems.
This was such a good introdyuction to coding! Thanks for making this?
agreed this was kinda fun
what was your solution to it
o thanks for the comment buddy! Glad you agree!
well... I kinda just... did it, you know?
how tho im curioustg
Well, I kinda just solved it with the code, you know? Where if you put in the right code, you get the right answer
i wanna learn tho
Well then, watch a youtube tutorial or smt
shush man
they move to fast and are too complicated tho
tbh im starting to think you havent done it
just tell him how to did it its not that hard
@darksloth18, be nice, we're all learning something new on our programming journeys. @CodingLearner95, you've got this! I'm sure you'll find some useful tutorials out there, and keep practicing katas :)
thank you this has motivated me and i just did a 7 kyu
Good job codinglearner96! You are really growing as a coder!
THANK YOU :))))))))))))))))))))))))))))))))))))))))
but how did you do it ClabeBARERBEBRE im really proud of my solution, imagine we did the same thing XD that would be really funny and cool. Also how much is it to rank up to 7 kyu

RISCV Translation to invade hobovsky translation monopoly! LoL
I am not doing translations as much as forks which change existing translations, because I am running a small experiment and I picked this kata as a guinea pig: I want to turn it into an example of authoring practices so others could use it as an example to guide new authors about creating kata, tests, setting up snippets, etc. Whether it will work out well or not, we will see. I have not finished yet :)
If you want to make your translation conformant with the idea, please take a look at tests of C or NASM translation and make this one as similar as possible w.r.t. orgaization of tests, test groups, feedback on failure, dedicated generators for various types of inputs, etc. I can write a comment on the translation with explicit points I would like to have changed, if you want. If you don't want to, I can just merge it as it is and I will adapt it later.
Thanks for the translation!
Just noticed your message! Will answer you later... But defintely riscv is a different language with different opportunities and needs a different test coverage...
Approved, with a follow-up fork for unification with C and NASM translations.
this will give you correct answer
This is not a kata suggestion.
that means "you can do anything to take correct test case" there is no procedure for that
The kata
suggestiontag is for when someone has an idea on how to improve the kata. It is not about providing guidance to the coders solving the kata.Maybe the op means i broke something in some language and tests always pass? :thinking:
Turns out their only language is Java, for which tetsing functions normally.
The print is not needed in the body of the cycle. create a common variable for return and assign to it variables to which the values Even and Odd are assigned.
why my code does'nt work someone please explain me what's wrong i did
We don't know what your code is, so it's hard to tell, please read this: https://docs.codewars.com/training/troubleshooting
You passed this kata in Python so I'll close the question because maybe it's not valid anymore.
It's my first time using this kata so I was pretty cofused at the begining. the function head is already given, just write the operation you will use to find even & odd numbers with return statments and don't forget to make the first letter capital. hope this helps!

kata hint != kata suggestion
I didn't like this Kata whatsoever. My code was wrong because it didn't have uppercase letters.
okay... but the tests tell you that, and fifteen seconds later you've got it fixed

why are you returning the i, its like you go to a shop and when asked the shopkeeper is giving the money to you again without giving the goods. return the answers not question.

3 times i do the same logic for even or odd at first and seeking for wrong capitalize letter but it seems like no error should appear and i see hint answer it is same as i do, but after i code on my self editor and see the auto format in code like if else should be end with end syntax. LOL i just forgot end in the end of my if else:")

Acho que o que codewars vai testar seria o return da função, então desde que a função de o retorno correto "Even" ou "Odd", é para funcionar. Basicamente, não use print
"Odd" and "even" are the wrong way around. Thats why it's not working. It's asking for the opposite in the question.
What's the other way around? Do you know what odd and even mean?
The tests are fine.
Nope, my bad you a totally right. I read the question wrong. For some reason I thought the question was asking to do the opposite. I got it correct regarless. its 00:00 over here, its way passed my bed time!
I realised thet print func isn't a solve. solve is in return function
Yes, that's written in the Troubleshooting
Nice, you fixed the errors I was getting. GG WP
Iam very bad with this
Good Kata! There is nothing worng. You just need to read carefully :)
there is something wrong with the test cases as they not compling with the instructed code
There is nothing wrong with the tests. The function's name should be
evenOrOddnoteven_or_odd. Not a kata issue.I used way to long for this, Overthinking it. Its natural i think to complicate things more then it needs to. Its a very simple solution, it might take you some time to solve it, but its a good practice.

if your forloop starts with number = 0 then number > 0 will never be true so your code will allways return "Odd"
THE PROBLEME IS WHEN YOU Don't USE CAPITAL LETTER IN TE WORD "Even" or "Odd"

You're printing instead of returning. Please read this article that explains how the codewars trainer works.
Also, you should use appropriate formatting (code blocks) when pasting code.
my code seems to work but it keeps failing. I guess the problem is in the way i'm displaying the code but can't find a way through it yet

i dont know what to do 😭
Helps us help you then, the instructions are pretty clear imho, what is it that you don't get?
You know hopefully that it needs to take a Integer and decide whether it's even or odd. How do you know if a number is even or odd?

Hello i need help pasting my code into code wars. I solved the problem in my ide and it works fine but if i upload it onto here i get an error. This has happened for two different problems. Thanks
If you're using Python it probably has something to do with indentation.
You passed this kata in Java, better read troubleshooting guide and post in those katas or check the Discord channels.
Expected and actual are reversed (in Python).

You are right, and you are wrong.
You are right that there can be more than one way to solve a problem. There is more than one algorithm to determine whether a number is odd or even, and your algorithm is a good one.
You are wrong that you can write whatever you want and it should be accepted, because when programming, your code usually has to conform to some interfaces or protocols. It can work however you like (almost), but it needs to communicate with other parts of the system in a predetermined way. You can rant as much as you want, but this doesn't change the fact that your code does not do that: it does not conform to general requirements of a Codewars solution. And it's not problem with just Codewars, because whatever code you are going to ever write, it has to fit into other places of the system like a jigsaw.
For some details, please check if this article is helpful.
Description: "Create a function", OP: pRoMpT()
Did you bypass the coding challenge to be able to register here somehow? It should've showed you that you're meant to write functions that return things to solve katas. Additionally, when you enter a kata, you should see a template of the function you need to write. Ignoring all these things leads you exactly where you are.
for some reason it only lets me relly to you b1ts but how am i even supposed to know what a kata is i never came across that in java scrpit and i couldnt use regular prompt because it kept saying funtion not defined the template had mad extra irlavent code that noone who solved it used lol what are u saying right now and tes i bypassed the challenge because it was broken for me apparently because how woukd my code work other wise?
Did you check the page I linked? Is it understandable?
hobovsky i get tht but how does my code not fit into the parameters? because i didnt know there was a even or odd funtion ig thats idk i never seen an evenorOdd funtion before even a little hit would have been nice but i see your point for sure
The
evenOrOddfunction was there in initial solution setup when you enter the trainer for the first time for this kata, or click RESET. When I enter the trainer, I see this stub:I think it was presented to you too, but you didnt know how to use it, so you deleted it and replaced with your code. Is this possible?
yeah i checked the link thank you now ik but it still dosnt explain why when i put in my code it said it was wrong and also gave me no bug fixes like it shows in the examples the test code also said nothing about an even or odd fucntion its still very miss leading how can i do it there exact way if i the way they want me to model after isnt even anything similar to the final result lol its like a bait n switch
nah didnt show evenorodd on mine could be mistaken though i was bashing my head into a wall for a while everythings hazy at the moment
It said you were wrong because you are expected to return a value, not print to console.
kayleighWasTaken thank you, so i was supposed to make it return a value with no input just a random number?
The general structure of a Codewars problem is that the tests call your function with dfferent inputs and check that it returns the correct value.
This is for consistency (it would be bad UX if some Kata expected you to write to console, and others expected you to return a value, etc. The reason for this being the chosen format is that most langauges unit-testing libraries are structured like this, making test writing for most of them easier.
I don't think there is an issue with my code, because the output seems correct, but codewars shows an error. PS. My code is in the replies. Please help!

Your code is not exactly correct, and your function does not return correct values even though it seems to.

Additionally, please use code formatting when posting code snippets: https://docs.codewars.com/references/markdown#code-block
you can't use printing on codewars. you have to return a value. returning is basically just assigning a value to a function. you don't need to use input for codewars either, it gives you a parameter which is essentially just a variable that can change every time the function is called
I tried posting my own code to this problem and its giving me errors when I know its 100% correct to find even or odd? How come?
Please see if this explanation is any helpful. It's currently just a draft, and I am looking for ways to improve it.
I'll check it out, thank you!

I think in the testcases there is a issue why should the undefined value return Odd?

No it doesn't, read this please: https://docs.codewars.com/training/troubleshooting#expected-the-same
Instructions are not clear. It appears that it wants you to create a table named "output" with a column "is_even" and that is not the case.
In JS test fails but all of my answers were correct. I lost a lot of time on this, thinking that I'm dummy :((((
Your current code passes all tests, there is nothing we can do without more info.
This test fails even though the answer is correct. I ran the same test cases that the program would run outside of codewars with all of them passing, yet they all fail within codewars.

failing the tests despite the code running well with different use cases outside of CodeWars
Read this: https://docs.codewars.com/training/troubleshooting/
I have. Still, nothing.
However it's not an issue (= a bug in the kata).
You have to return the result, not just print it.
This comment has been hidden.
Not sure what your code is, but Xormias is saying that the kata requires you to build a return statement within the function as opposed to printing out the result to the terminal. Additionally many challenges may actually fail if you leave print statements in them due to the way they are built to be checked.
This comment has been hidden.
Because that's what the kata's description says. "Even" and "even" are two different strings. And please mark your post as having spoiler content next time.
Thank you. And I will flag spoiler alert next time
Yeah that got me messed up as well lol. Felt like a trick question but I guess we gotta pay close attention

On Codwars, input values are provided to your function as input arguments. You are not supposed to read anything with
input.numberis already the value you should work with.OP solved it, closing
Thanks a lot. I've resolved the problem with your helpful comment.
Easy and good kata!
This comment has been hidden.
It would not work for the kata because your code overwrites the variable number with the result from int(input()).
OP solved it, closing

@DainPark-web: Please don't post solutions in Discourse. Code must be posted with a spoiler flag (which makes it invisible to the users who didn't solve the kata). Someone put the flag for you this time.
@nicholasjperry: you have to
returnthe result, not print it.Yikes, sorry. Thanks!
Very nice kata for begginer practice.
My code in python in VSCode is correct, but here fail. This kata ir wrong.
how exactly is the kata wrong?
Please read this article and see if you can find anything helpful there: https://docs.codewars.com/training/troubleshooting
OP solved it, closing
Read the instructions carefully, it says return, not print

you're not supposed to get an input for the code
the function
even_or_oddwill be called with an argumentThis comment has been hidden.
Because your function should return the result. Read this: https://docs.codewars.com/training/troubleshooting/
Please use spoiler flag when you post code.
Please use markdown format tags or it's unreadable, see there: https://docs.codewars.com/training/troubleshooting/#post-discourse

Yeah I was thinking this would be the best way to solve it too, thanks for your Case hint helped me to find the solution
OP left the building
Negative numbers are not tested in Haskell and should be added to sample test as well
Negative numbers are ( possibly now ) tested in random tests.
Fork with negative numbers in example and fixed tests.
Fork was approved.

wrong function name ~~
okay but even when I try with the correct one it doesn't work, why?
This comment has been hidden.
what errors are you getting. Also I know its implied by looking at the syntac of your code but always include the language in your write up.
Thank you! This appear: Time: 897msPassed: 0Failed: 45Exit Code: 45 Test Results: Log even Sample tests 2 is even expected 'even' to equal 'Even' Completed in 2ms 7 is odd expected 'odd' to equal 'Odd' Completed in 1ms -42 is even expected 'even' to equal 'Even' -7 is odd expected 'odd' to equal 'Odd'
Ii don't know if there something thara have to be with the sample test?
in expected 'odd' to equal 'Odd'
...
(yours is not capitalized)
Thank you!!!

Your code being wrong is not a kata issue, those are different operators.

Answered then by your acquaintance. Marking as resolved.
I wrote my code in Js and it worked fine in my Vs, I cant submit my solution on code war tho :(

Sample tests is a tool that evaluates some values as inputs for your code without counting as an attempt. Depending on the type of kata it will compare your code output with the expected result.
When you click on "submit" a whole lot of tests are executed making sure your code don´t break. It´s kind of the same but with random values or at high volumes of data.
So does the syntax have to be perfect for the sample tests to work?
COBOL translation

why the hell is this even 8 kyu.
Doesn't work even with the exact same code, litterally. Like, screened the answer, put it side to side with my solution, no difference whatsoever, and doesn't work.
I feel like there's a bunch of context missing in this comment.
Do you want my solution? Or do you want me to precise that I tried with Postgre ? My solution was clearly the exact same as the first you find in "show me the solutions", hence my confusion.
Do you mean, you tried a solution which you found in the solutions tab, and it didnt work?
That might be because the solution was submitted with an older version of the language
Ok !
My solution was like the first one in the solutions tab
Postgres:
Is there an expected ordering to results? The mapping of strings to numbers is correct but I think results are checked in a different order than I deliver?
There was a bug in the kata which got (hopefully) fixed.

You gotta return the result. Console.log only writes things to the console, it doesn't actually send it to the test output

You're returning
"odd"You missed " in Even

Hi! It might seems as a stupid question but whenever I try to submit my solution, I cannot. The Output window displays errors from the sample. The code works as I compiled it before and tried it. How should I go about properly publishing my solution?
What do the errors say?
This comment has been hidden.
The error is a result of the user modifying the initial solution stub.
Closing the question as obsolete, please post a new one if something still needs explaining.

Please read this: https://github.com/codewars/codewars.com/wiki/Troubleshooting-your-solution and mark your post as having spoiler content next time.
You have the sample tests to play with, see which one your code fails, fix your code.
Thanks , I solved it

You have to return, and not print the string
yeah, thanks! I think I've just figured it out

Your oddness test is wrong, and gives false negatives.
Ahhhh, I realized now, because of negative numbers... Thanks!
When I run the Same code on other editors it runs perfectly. But here it shows an error.

You need to return your answer, not print it.
It would generally help if you mentioned which language you were having this problem with, and properly marked up your code. I'll give you the benefit of the doubt that you added the
Spoilertag yourself.Available documentation includes a troubleshooting guide, which includes those guidelines. ( It might or might not include the thing about
returninstead ofprint. But I think it does. )My solution worked in my test, both here and in Visual Studio, but I get this error when I Attempt:
Test Failed Expected string length 3 but was 0. Strings differ at index 0. Expected: "Odd" But was: <string.Empty>
What am I suppossed to do? This site is quite confusing for begginers.
Please read the troubleshooting guide.
When you've read that, and still can't figure it out, please post a new question with a mention you followed said guide.
Closing.
Why can't I make use of "print" to output the results? The "print" is not highlightend by the IDE. What happened? By the way, the codes were done with Py3.
Since this is a function you have to return a value. Write return and then after write what you want to output.
oooops！I see. Many thanks!
is postgre don't know 'IF' statement like mysql? i can't use it here.
No, they're different, you can read about postgresql here: https://www.postgresqltutorial.com/
okay sir, thank you!
Hello. My code keeps failing one test here but works find in my shell. Any ideas? Thank you
Please refer to the troubleshooting guide.
If you've followed that and still can't figure it out, follow the guidelines also in there to post another question.

Please don't post solutions in Discourse.
my test works perfectly on jupyter notebook (working with python) but somehow i keep having errors on codewars
Not a kata issue, read this
No random tests.
Which language? At least Haskell, JavaScript do have them.
coffeescript, python, ruby added. Still missing for
Done for C++.
Done for C#.
Done for Clojure.
Done for Dart.
Done for Elixir.
Elm tests use Fuzz, which is a property-based testing framework. It runs tests 100 times, every time with a value generated randomly by one of four generators. Test output is quite terse, so test output panel might make an impression that there's not many random tests executed.
Done for Haskell.
Done for ObjectiveC.
Rust had the tests added some time ago.
Done for Shell.
PureScript has QuickCheck-generated random tests.
Random tests have been added to all languages. I'm closing this issue, please rise a new one if I happened to miss something.
Python tests are using
Test.expect.Fixed.
why its showing EOF error? I run the same code on different IDE but it works there? Any explaination?
We do not get EOF error, so we do not know :(
My guess is that you are trying to read input from console, are you?
I had the same problem, I was getting the user to input data, but you can just a set number.

Don't post solutions here ! There's solutions tab for it. Also, use spoiler flag if you're gonna post code snippets.
So sorry! Literally noticed that right after I posted. But for some reaason, the solutions page wasn't unlocked, even after I solved the kata. Any help there? Sorry again!!

Check the last bullet point if this FAQ to get a hint on returning the answer instead of printing it.
You're not returning anything.
thank yu guys :)

return, not print. In almost all katas, your function should return the result, use print only to debug your code, and the log will appear above the test result. Read this for some more info.
Thank you, bro. Helped a lot!

Hi
not a suggestion. don't post irrelevant content!

Hi VitaliKarpuk, in case you didn't know, it's forbidden to post code like that because everyone can see it on the dashboard (I have added the spoiler tag)
My code passes 6 of the tests, and all of the example tests. The test won't show me what it's passing that is failing; so I'm kinda stuck at this point.
print the inputs

Your functions should return in CW instead of printing the result, you should know that by now, don't you?
