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.

Glad to hear it! If it was up to me, I'd say it's 5 kyu due to the time it takes to write down key mappings and to come up with working algorithm through trial and error, etc, but the standarts keep rising on CW, so expect something like this to be the new 6 kyu ;)

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.
