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.
Now your solution doesn't look like a cheat :D
Wow :( This is sad... I believe admins should give ability to improve Katas at least for the owners.
Anyway, thanks for the nice Kata, Nick.
Random test cases should be added for sure. At least for JS. Was going to compare my solution with others and found so many cheats...
