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.
Great idea, can reuse last check.
Typically this solution get best running time, but rarely it get worst than 2 for loop statement (slower than 100 * times). Try to run this 1000 times and get 1 worst case.
Great idea only take 1 for statement :).
