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 agree.... This may be much easier for anyone who has written a compiler or taken a compiler class (I have not).
I set a goal of solving one kata a day of thinking I could devote a couple of hours each day. After spending over 6 hours solving this one, I'm rethinking how practical that goal is.
