Same problem in java, still for max(5), i get 47, which is not correct

It's still giving me issues.

See below

@Orbit3v1 good catch ! (That's what happens when you try to code late at night :) ) I've updated the solution. Should be fine now.

As far as I know for n = 5, test 2 expect 47.
The fixed tests are the same in all languages and 175 guys passed the kata.
Did you notice in the description:

4: p(n) with parameter n: returns an array of n unique prime numbers (not tested)

5: maxp(n) with parameter n: returns the biggest prime number of the sequence pn(n) # (tested)

well, the test case 'test2' expects 43, while the max item is 23. Exacly the above issue, but in the C# testcases

Can you post the test output?

Still having this problem in C#.

Please can you be more precise, I don't see where the problem is:-(

This is still an issue with the Haskell test cases.

Forgot to resolve issue.

Oh, sorry for that and thanks for noticing. Should be fixed now.

My solution passed this test correctly so it seems that you make a mistake in your code.

Oh, my friend said that he has proposed Haskell translation, but I don't see it.

I saw his Java translation and your Ruby one, but didn't saw the Haskell version O_o

Where can I find it?

If you are talking about the example test cases, they are not updated for users who already attempted the kata (if so, it would overwrite their own tests, provided they wrote some).

Also, notice you still have a Haskell translation pending; approve it if you wish, otherwise any edit to the description might give troubles later :)
