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.

Great solution ! Would be even better with a representative variable name for your string (ex : answer).
Oohhhh, I didn't know you could just add the char values directly. I converted them all to ints first. But I guess the chars are all just int values behind the scenes, huh? Nice to see the same solution with fewer steps.
