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.
It's usually better to comment the solution instead of the kata. The best solution might change over time, and then the explanation won't fit the solution anymore.
Can Anyone explain me the best solution, I mean with "format"? thanks a lot.
