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.

Ahh I see now, was wondering how they could possible use "<" operator when comparing an int with a string. My mistake.
well now i just feel silly
The input is not an integer in the first place, it's string. That's why it's iterable.
i thought you can't iterate for integers, how is this possible?
I can never understand these...
I was wondering how you'd be able to flip the letter being added, that is clever!!
I really like these variations. Maybe I just have neanderthal brain but I find them so easy to read.
its beautiful....
