Day 5: Cafeteria

Puzzle 1 took me 30-ish minutes to figure out. I initially tried building an array of numbers from the ranges, but it turned out to be much easier to parse each range against each value and let the machine do the math.

Puzzle 2 seemed pretty straightforward, and I thought I had a simple solution, but it didn't work, and an hour later (1:30a), I have to admit defeat for tonight.
