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.

Sorry, I was mistaken.
I thought, if the final key is 10101, the result shows 101 instead of 10.
But the final key could also be 1011011...
shouldn't be result 101 or 121 rather 10, 12 ??
