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.

Not looking for a solution, but rather a bit of "light" in terms of performance. I'm using C# and came up with a one liner lambda that passes the preloaded tests no problem but fails on the large ones in the final set for taking longer than 600ms.
Is linq a no-go here?
