What does (n) represent?
This comment has been hidden.
the initial code in C should be a function definition, not a function declaration
fixed
If you are here and still can't solve this kata, try to read task very carfully and use fingers. it will help for sure!
Love this Kata
This Kata is joke, i used test cases to understand problem.
And where is the suggestion?
Description is awful, just read the test cases.
This honestly needs to be pulled. The description does not make any sense. Plurals in English do NOT include halves or zero.
0is plural in English; for fractions it depends on the noun that follows: "half of the pie haS been eaten" vs. "half of the pieS haVE been eaten". in any case, this is a 8-kyu kata, not a grammar exercise.I solved this kata, but I had no idead what the kata wanted

Adjust description, please. Hard to find out what i need to do
Terrible description, explains absolutely nothing
The task description is idiotic! Why indicate “pay attention to English grammar” if we accept numbers and not words as input!!?
Needs a better description and more examples
No random tests in Java.
Fork
Merged
Ruby should be updated to 3.0
Enabled in this fork + improved random tests
This question is grammatically incorrect, numbers (or at least rationals) on the interval (0,1) should return false not true, it is "half an apple" not "half apples".
Fractional numbers are handled differently, it's 0.5 apples.
why would you add 's' when there is nothing.
nothing is infinite?
instructions not clear. no sample input and output
You have to clearify your task more. It's not so obvious what you need to do when you're reading it. I've read 10 times to understand what I need to do. Also add more tests to show what should you do.
Lua translation ready for review :)
There may be an issue with the randomized tests in Elixir: they appear to expect a boolean instead of a string.
Problem says that you will only test
floats, integers and zerobut test cases include stringInfinity. Also part of an object is singular in English. Half ofanhour, three-quarters ofasandwich.The singular for parts of an object is only true if you use fractions in English. You would say "half an hour", but you would also say "point five hours". "Three quarters of a sandwich" becomes "point seven five sandwiches".

Not a kata suggestion (don't post code without spoiler or as suggestion next time)
This kata will be more difficult in Russian I'll give it to my students.
Please review my Rust translation :) https://www.codewars.com/kumite/617663830a9ae1001aa15dea?sel=617663830a9ae1001aa15dea
Approved :)
(next time you propose a translation for reviewal, you'd better put a suggestion flag to give it more visibility)
Thanks. This was my first one. I really appreciate your help.
My pleasure. Hope you will populate soon Codewars with new Rust katas, they are missing!
what the hell, i didn't know till now that ki "0 and 0.5 is plural".
i was wondering why they used a float. now i know.
Thats noob friendly.
it is just a simple grammar set : -when i say : one apple ->this doesn't need a plural -for a number different for 1,it need a plural one apple ,5 apples ,5 minutes *in this article,you will find more informations about this grammar issue : https://alistapart.com/article/pluralization-for-javascript/
Just as an English teacher, I need to say we don't use plurals for decimals(parts of one whole). I don't have .5 of apples; I have .5 of an apple.
I know, very useful.

YOU're not returning true or false; you're returning a string.
From the description: "It should take a number, and return true if a plural should be used with that number or false if not."
im not used to the synthax in this website. so annoying. it was so simple! thanks!

Or you can modify the generator so that it can alternatively returns a

Hidden Tests in Java check for negative infinity and NaN when the description claims that all values will be positive or zero.
Sorry about that. I've removed those tests for you. If you could go in and add random tests similar to the JavaScript ones I'd be much obliged. I tried to do it myself, but don't know enough about Java to do it in under an hour XD

This started happening last night after 1:00 AM (GMT). Rechecked again this afternoon 2:00 PM (GMT) but still the same situation. Found a few questions on this subject but only after drafting my question as below:
Any update please?
Currently Codewars platform is experiencing issues.
https://github.com/Codewars/codewars.com/issues/893
This test fails for me:
infinitTest(PluralTest) ✘ expected: but was:
any clue?
Which language? And could you give me your code between code tags, please?
``` code here ```
This comment has been hidden.
Same problem.
Interesting. I believe there may have been a bug where the
<true>and<false>became HTML tags accidentally; but it looks okay for me at the moment. I just tried your code and got:expected:<true> but was:<false>.I've added messages to the tests all the same. Could you retry and let me know what you get?
Now I get: infinitTest(PluralTest) ✘ NaN expected: but was:
Okay. If you right-click that line of text and click "inspect element" it'll show you in the dev tools what that text should be. That'll help for now until they fix the bug.
NaN expected:true but was:false
I thought I remember learning in English class that fractions less than one were considered singular. For example, 1/2 minute or 1/4 apple versus 1 1/2 pies.
That is true. Though
0.5would be said as0.5 minutes, as a plural. That's why I left it as I did. Good comment, though!TypeScript-Translation kumited!

Please check and approve it! ;-)
C translation kumited! :)
Sorry, but the description is misleading.
It says
You only need worry about "english grammar rules", but then the test cases throw English grammar out of the window and invent their own solution requirements.What about:
ssoutsideswho are native English speakers?http://english.stackexchange.com/questions/38293/why-is-zero-plural
The problem of zero would be moot if the tests were not testing for it. The description states
All values will be positive integers....so why is zero being tested at all?The tests do try
0, so that's covered. I've added a note to the description to make sure it's clear that zero can be tested for.I'm not sure what you mean about the grammar rules being ignored. When zero of a thing is spoken of, there is a plural "s". And that's what is being tested for. Could you help me by saying what I am not doing correctly? And what I should be doing?
Doh. I'm an idiot. Very sorry.
Explanation:
The Java test case assertions have no messages and there are multple test cases in the single @Test. When my first attempt failed with the vague error
expected:<true> but was:<false>I wrongly thought it was the 1st assertion (the one with the zero) that had failed.Lessons:
Kata tests with multiple assertions can cause confusion because if they fail with no mesasge you don't know which part failed
I need to pause and think more before raising issues :-(
Ah, I see. No worries.
I definitely agree on that first point. I try to add useful messages to every single test. But I only write the original JavaScript tests, unfortunately.
C#-Translation kumited!

Please check and approve! Every translation is a chance for you to get more honor-points and good for the community. :-)
Sorry for the late response. Didn't see it in my emails or something. Thanks for the translation!
Thank you! :D
Hi, I've added a CoffeeScript translation, if you want to approve it, instructions for the approval process are here.
Done. Thanks for your help.
Python translaton added. Please approve.
Doesn't show up when I "edit" the kata. Not sure where else I could look?
Click on 'plus' icon above, near the language icons, and choose the Python translation. Click on it, find the green approve button in the upper left corner.
Ah, I see. Approved.
Is that from the
kumitesystem, then?Yes! Thanks.
what it a plural,can we make things easier to understand :(
You should probably grab an online dictionary and look those words up. That being said, the kata contains all rules that are necessary to solve it.
I've added a little note. Basically, in english,
1is singular, all else is plural.thanks a lot .
Sorry for my attitude :)
That's alright, mate.
Test Passed: Value == true Test Passed: Value == true Test Passed: Value == false Plural for 100 - Expected: true, instead got: false
why do we need a plural for 100?
Because you have 100 boxes, not 100 box.
What do you mean? Because 100 is more than 1, and therefore it should be PLURAL... one hundred appleS.
This test seems incorrect:
Shouldn't it be:
It doesn't affect the outcome since your just testing for true or false, but it might lead to some confusion
Probably... though it should probably actually be something like "1 should not be plural". But after a certain point (number of solutions, maybe?) CW locks the tests so the author can't invalidate a ton of previously-accepted solutions. Thanks for the suggestion, though.
thanks, jsdev... I guess I just don't understand what Test Fixtures is about at all.
what sounds better? "-1 car" or "-1 cars". I think the latter.
I agree. I only test positive values (or zero), as negative values do not make sense as a quantity of something, and so cannot have a "plurality". I've added a note to the description to this effect.

I'm not sure I understand what you mean here... The solution you provided works as expected, and the tests are all correct as far as I can see. If the tests fail, they should print the error message along with the expected and received values that are not matching.
Could you tell me what you think the correct answers should be for each test?, please?
