Loading collection data...
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.

They're better now. The ones with only 1's made me think you wanted squares with only 1's at first instead of the number as a square.

There should be some leeway regarding the tests. For example, [1] and [1,0] are the same polynomial but only [1] works as a valid answer.
Examples could be better.
