Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.

Very short code for this problem. But if this solution passes, the time limit is too high. The string copy operation makes it O(n^3) instead of O(n^2). This is only codewars, but the title says performance :D
Excellent kata !
Nice kata !
