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.

I'm getting the same as everyone... random testing fails for whatever reason... Have to keep hitting Submit until Kata passes or else will just skip this altogether... :/
There's a typo in the description which says "an valid array" where it should say "a valid array". Other than that, nice kata. It could have a few more contraints though!
