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.

However, I checked it in Pycharm using timeit module and it is 3 times slower than just simple mapping through array using [row][col] indexes.
Way too many unnecessary actions for the code that can be written in one line and more effectively.
