[https://zigbin.io/1fff88](https://zigbin.io/1fff88) Ok so I failed part2 of day 17, 21, and 24. I don’t really feel like looking at people’s solutions and try to finish, so that will be it. Congratulations to p88n who came up with extremely performant solutions and awesome visualizations. That was a fun aoc, see you next year!.
