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.
when you realize your mistake and pass the kata, please come back to close your issue/question. (and ask questions when you are not sure, if there was such a big mistake in Java 10,000 would not have completed it)
It's not impossible.
Not a kata issue.
