> Then again, this is nothing like the type of problems I work on a daily basis. I thought it'd be fun to take a stab at it in Python, which I haven't used in a while, but only barely still remembered that I could accept command-line input with the built in `input` function, something I don't think I ever used after writing my first lines of code 15 years ago. Then I figured I'd use just lists instead of a numpy array but had forgotten that [[0] * 4] * 4 would just create 4 references to the same list. And that pretty much derailed the whole thing for me, even though I was sure I'd get it done in 25 minutes or under :-)
