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.
Why the output is
["only", "solutions", "some"] instead of ["solutions', "some"]The test:
"only some solutions are answers"Descriptions says: Group them by their beginning!

So in the case of
