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.

Agree completely. In the workplace I would use itertools, but for this challenge I decided to do it the "hard way". Was trickier than I thought and a fun bit of optimization challenge.
Best of luck!
I was working on a timed coding challenge for a job today, less than 24 hours after completing this kata. The challenge involved finding permutations and combinations. While I did it the "hard way" to complete this challenge, for the time crunched interview, I went straight to itertools!
