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.
Of course, as you please. It's just a way of bounding logic together for good readability

Random test seems to be not extensive enough, failed once and with the same code I passed the tests in the second try. I did this kata in C++.
