# AOC 2022: Solution for Day 2

My solution for advent-of-code day 2

Today’s challenge took a lot more code to solve than my solution for day 1. There’s just a lot of conditional branching going on. As far as I can tell that’s sort of inherent to the classic “rock paper scissors” program this is based on, though.

That said, I’m sure there’s a “cleverer” way to solve this, with probably less conditional branching code-mess and more maps with pre-defined scores. That said, this was the first thing that came to mind when working through the problem organically. It works, it’s mostly readable, so it’s what I’m sticking with 😎
