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.
Please see my solution and guide me.
The only possible way to optimize is to use for loop instead of recursive.
But recursive version is more understandable.
Using recursive and got "Process was terminated. It took longer than 12000ms to complete".
//PHP Version
Test cases in PHP are wrong.
