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.

i didn't start this kata because i think that tests are incorrect. for exaple one of them gives you 2017 and expects 2071 but 7210 is bigger then 2071
