Yesn't, Char is an instance of Ord where the characters are ordered by their unicode codepoint. It does not really "threat them as they were numbers" but deep down at some point everything is an int eventually.

wait, Haskell treats chars the same way as if they were numbers? like, he automatically converts char to number like ord() in python?

Rust: The error message for the test_large test case isn't helpful as it doesn't give any indication as to what's being tested or what failed to pass: "assertion failed: result == expected1 || result == expected2".

Could this message be made clearer/the test input be posted in the comments?

Actually, sorting identical items should be fast, so I think it's not sorting that's supposed to be banned, but quadratic solutions.

The performance requirements are not matched in this translation, the arrays are very small.

I didn't notice that there was a Haskell translation removed before:

Could you add some really huge array? For make solutions with sorting fail on timeout?

Can you add them in a fork?

My bad, I didn't get an email notification from this comment.

Haskell example should be added to the description.

Approved

Use console.log() in javascript.

By printing them out?
