Advent of Code 2020 Solution Megathread - Day 9: Encoding Error

Ryan Palo - Dec 9 '20 - - Dev Community

Whoo! After yesterday's palate-cleansing interpreter, I'm ready to move on to new things. I'm managing to stay on top of this year's challenge so far, and I think it's the longest I've managed it so consistently. But we'll see how things go. We're not even halfway yet.

The Puzzle

In today’s puzzle, we're tasked with finding a weakness in the XMAS data cypher system (which consists of streams of numbers with requirements about sums) by finding the number that doesn't fit the pattern. As long as it doesn't have a big complicated string to parse, I'm happy.

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.
