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.

Thanks. It's really not a big deal, I overengineer sometimes too. I think the wording in Kata prompt certain approaches -- like the graph approach. I try to find novel approaches and this one struck me when I was thinking about properties of triplets.
Nice, I really over engineered my version (polite way of putting it). This is clean and simple - no idea where my mind went!
