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.

I guess 8kyu for the long way, but right way is definitely at least 7kyu
I do not believe this is 7kyu and my answer was NOTHING like the common answer. Also, this example is very strange because in what world are people entering PINs like -1.234?
Are we trying to learn to code or doing a math class? why test giant numbers that require optimizaton of code on a 7 kyu?
absolutely no reason for this to be 8 kyu or have that high of a satisfaction rating. this isn't math class what are we doing?
As a beginner, this solution is faster for me to write while staying extremely readable/understandable.
