advent-of-code-2020 VS adventofcode

Advent of Code is a good opportunity to learn a language that you're curious about, but that's not the only way to do it. Some folks focus on learning algorithms, using a language they're already familiar with. Some folks focus on making interesting visualizations. Some folks use a language they already know and focus on getting the fastest possible execution time. Some folks try to get the shortest possible program, or visually-appealing source code. What sounds like a fun challenge to you this year?

Day 24 in Kotlin

This one was interesting! Part 1 wasn't too hard aside from me mucking about with a data structure I created pretty poorly. Then when part 2 unlocked I found out that the part 1 solution would take about 60 hours to find a solution :D So back to the drawing board. I had to implement a data structure (referenced in the code) from scratch :D
