Advent of Code Using Tidyverse

When I find the time, I like to try solving the Advent of Code puzzles. I prefer to take a “tidy,” data-like approach wherever possible (because that’s all I know). Let’s see how far that gets me this year.

Day 2 asks us to find numbers that contain patterns (like 99 or 1188511885) within ranges of numbers. This task is very friendly to a tidyverse approach. We need to do some data wrangling to get everything in the right format, then it’s just a matter of a simple regex to find what we need.
