Random test array's size should not be fixed to 100 in

• JS

• Python

Thanks!

Fork that adds ["","","","",""] as fixed edge case.

Missing fixed test for

• ["", "", "", "", ""]

in Haskell

A great exercise that utilises an extremely useful function.

Approved some time ago

now that i see my mistake feel like an idiot , thank you for helping! still learning :)

String is immutable in Python, so you are returning the original array despite you have reassigned each string to be the correct format

Your solution fails for cases like ['a', 'a', 'a'].

OP solved it, closing

The first non-working code is you will return the result as a string after the first iteration. And the last line of code will not be reached (unless lines is an empty array)
