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.

Hi,
It seems that when I do the rotation in-place the second test passes the transformed array to the next test thus affecting the tests. Is it ideal to create a copy and makes changes on the copy rather than the original?
I didn't quite understand this solution. Could someone break it down a bit?
