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.

Interesting. Thanks for sharing!
I don't know much about java, but I think the only way is to declare those classes private inside the main class (Leetspeek class in this case).
I can't really understand your exact question x/ Could you explain it? There is no 'app' here, just tests :X When you hit test / attempt, you are running the code, so I'm confused what you're asking :P
Your reduce method has incorrect condition. Try using
System.out.println(n)to debug it.
