Advent of Code 2020 Solution Megathread - Day 4: Passport Processing

Ryan Palo - Dec 4 '20 - - Dev Community

Day 4! I was worried as I was reading the first problem yesterday that I would have to optimize for any rational slope. I'm thankful he decided to take it easier than that for Day 3.

The Puzzle

In today’s puzzle, we're just trying to get through airport security, which is jam-packed because, obviously, Santa's magic keeps the North Pole COVID-free. It's classified as a hum-bug. 🥁 Anyways. The passport scanner is broken and we're doing a good deed by "fixing" it. And by "fixing," we mean "hacking it to let us through but also mostly fixing it."

Y'all. We are THIS close to validating YAML and I am here for it.

The Leaderboards

As always, this is the spot where I’ll plug any leaderboard codes shared from the community.

If you want to generate your own leaderboard and signal boost it a little bit, send it to me either in a DEV message or in a comment on one of these posts and I'll add it to the list above.
