I really enjoyed the difficulty of this one. Not too easy, but not insanely difficult either. I try to stick to 6kyu challenges and the degree of difficulty varies greatly sometimes. This one was perfect in my opinion.

After reading other solutions, I always wonder what the hell was I thinking.

Nice easy to read code.

A little tough compared to some of the other 6 kyu katas but definitely one of the more fun challenges I've solved.

At first I figured I would have to use the brute force method, but all of a sudden the solution came to me out of nowhere. This kata ends up being really satisfying once you figure it out, especially for a 6 kyu.

After spending way more time than I'm willing to admit and second guessing my intelligence every step of the way, I finally completed this kata. Damn good challenge and one of the more difficult ones I've completed.

Happens in python as well. I'm caught on the exact same infinite loop.
