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.
I agree to that.
Oh, I see. I get it now.
Nice kata. I think you should go without "The kata tests are the same as the sample fixtures.", though.
I was also going to propose this. Test cases over a million and with length multiples of three.
This is a very nice kata. I enjoyed doing it.

I don't think so. If the language provides the functionality, why not use it? It is a clever way to improve your code throughput and a valid way to teach others a valid example.
Wow, nice function programming Kata!
