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.
Get started now by creating a new collection.
First, requirements for size 8 contradict the ones for size 2.
Second, it would be a good idea to swap expected and actual maps, so that JUnit would not surprise anyone with confusing messages like "expected 0 but was 1", saying that about a wrong 0 that I've got.

It feels unfair that 567890 (incrementing nine to zero) is required, while 109 (decrementing zero to nine) is forbidden.
Anyway, thank you for this Kata!
