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.
meybe you need finish "How satisfied are you with this kata?",if you checked the VERY SOMEWHAT NONE ,you will get the points.
I think this Kata is difficult.I didn't use RegExp,It took me several hours to solve this problem.
I submitted my code time and time again.10 minutes later,I finish it.so you need to wait.
Maybe my first 3kyu Kata.
