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.
Well don't I feel silly!! XD

How are the difficulty values set?
I wonder if the true difficulty for any rated difficulty level tends to drift over the years. I.e. this puzzle is from several years ago; maybe 2kyu was appropriate difficulty ranking when it was written but is no longer so.
Reminds me of that old version of Tetris where you would slowly reveal a nude picture of a lady

I think you can train again and submit a new solution that overwrites your previous one.
Not sure I would have ever thought of this!

Assuming the author of this is Kata is also the author of the test cases, it's unlikely that the test case "should return 2 for input 1" is not as he intended. More likely he did not communicate his intentions clearly in the Kata instructions. I have added a comment to this Kata's discussion recommending that the author update and improve the instructions.
