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.

@kacarott when i click "attempt" it does not give me error , but it is not submitting
Approved
The sample tests do not test every input. When you click "attempt" you run against all inputs, so yes it is quite common for solutions to pass sample tests but fail submit tests.
I have tested the solution and have passed it, but when I attempt the solution it give me errors, is this a common problem?
