This solution is 4 years old you know, that's the only reason you keep seeing my solutions as well as many power users' ones

lechevalier, where do you find the time to complete every single kata that I do? Not only that, but you also get the most optimal solution on each one- I stfg I'm so sick of it. Stop posting. This has become personal, and I wanted to let you know that. Make me feel stupid one more time...

Honestly man, if we're not dealing with massive matrixes I don't think we really need to worry about time. Optimized code is good, but I've found myself spending literally dozens of hours trying to optimize code on the off chance that it's going to matter, just to realize that it, in fact, never mattered. If you have something nice and simple, and it works within the time constraint that we're working with, then keep it that way. We are using python after all.

It actually is

Nah I spent the last 24 hours thinking about this problem trying not to make it in over 50 lines, decided I just had to make it work in 50, realized it was harder than I expected, struggled to make it work, and then finally hit submit just to start slamming my keyboard on my desk when I saw this solution.
