I never ran into any problem. I had no idea there was any. I also have no idea why there was a difference between Submit and Sample Tests anyway.

ETA: it's probably a refactoring fossil

Approved. That made me nearly go nuts. Thank you.

Sample tests in Haskell fail due to a faulty function signature. I've put in a translation here that fixes it.

clear explanation @mortonfox thanks for that!

O(N²) => bad time complexity

It should have always had a performance tag.

Approved

LC translation

But isn't that the essence of haskell? I mean, is that even possible to make haskell fail, to match JS or python?

How could this issue be resolved, in your opinion? lowering the inputs in JS/python?

The definitions Haskell presents are for the newtypes which it requires. In Python and JS List and Pair are merely functions which follow the behaviour defined in ## Info (complimented by Preloaded definitions).

Regardless, I have added an extra section for a hopefully more concise definition.
