Well done bro, i'm struggling on that one xD !

I think you're not skipping the trailing white space.

When i do it on the console it all works, i get this output:
-> [' Gap ', ' gAp ', ' gaP ']
but when i test it on codewars i get the wrong output :'( :'( :'( :'(
It says : Should return: ' Gap , gAp , gaP ' - Expected: [' Gap ', ' gAp ', ' gaP '], instead got: [' Gap ', ' gAp ', ' gaP ', ' gap ']
Anyone else that me got the same issue? If so what did you do to get it done?

It is the only issue i've got with this really cool and funny Kata
