Thank you for adding the tests in the missing languages
I think there's only Haskell left without the fixed test case. I'm not really fluent in Haskell though.

Thank you for the report,
Added this test case to the kata

Thank you very much for doing the update yourself!

Updated to node 18, updated test cases as well

You shouldn't expect anyone to give you a direct solution for the problem ... that's the whole purpose of codewars : to find the solution yourself.

I don't think I can give you any more hints than "cound the number of pairs"

You code counts the number of colors that have a pair. But what we want is the actual number of pairs.
Hope it helps.

Hmmm I'mo not sure where exactly, so I added the #include <vector> everywhere

Approved, thank your for translating the kata !

Wow indeed, I'm surprised nobody pointed it out before.
It's fixed now !

Ok, fixed

So the idea would be to add the #include <string> pre-processor instruction ?

I'm not sure what you mean by that ?
Everything looks good to me.

Yes, I updated the kata to Clojure 1.8.0 and updated the tests cases

Indded, simpler this way.

Fixed, thanks for pointing that out
