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.
Cool!
Just wanted to point it out, since it was the most upvoted solution.
Yes, but it's 8 kyu. You can't expect questions on data size limits on 8 kyu.
Probably there should be something like n <= 1_000_000_000 in the description to avoid ambiguity.
Panics!
