@dinglemouse, thanks for the support haha (fan of your Kata btw :P), anyway it seems none of this matters anymore as the Kata has been retired. I'll be back with something better hopefully soon.

Ah, thanks for all the feedback dude, I'll definitely give this another go with a more interesting Kata sometime. This has been a good learning experience though!

fixed, added 200 random test cases :D

Thanks for the feedback, honestly I just wanted to try my hand at making a Kata, and this is some random idea that came to mind. Wouldn't be the worst thing if it gets taken down.
