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.

Maybe there is another problem, but your code doesn't handle case-insensitive.
Post your code using markdown formatting and mark your post as having spoiler content. Remember to mention the language you're trying and if you already solved the problem and it was not a kata issue, mark this as resolved.
