This is so clean. I had it in my mind to not brute force from the beginning, but I should've given up given that up given the input size as well. It produced a lot more readable code than mine

This is so similar to mine - but I am really having a problem with speed. I let part 2 run for 30 minutes last night before I just let it run overnight.

Need help finding good python solutions
I got all but one star in 2020 when I did it in Python: https://github.com/ednl/aoc2020 but I'm afraid there may be some short variable names despite not doing it for speed.

2020 Day 8.2 in Python - trying to figure out how to do this efficiently?
Day 8 runs in 0.02 s using python 3.9 on my M1 Mac Mini. Just flipping in part 2, no special optimisation. My code: https://github.com/ednl/aoc2020/blob/main/day08.py

[2020 Day 6 (Part 2)][C] Works on example but not on puzzle input. Can't figure out why.
Good that you got it working! My version in C is a bit shorter, perhaps you could use some ideas for the next puzzles? I like the dynamically sized getline() function, for instance: https://github.com/ednl/aoc2020/blob/main/day06.c

[2020] Optimized solutions in C++ (291 ms total)
Day 23 part 2 in 0.06 s on a dual core 1.3 GHz i5 Haswell (2013 MB Air) https://github.com/ednl/aoc2020/blob/main/day23.c because of a simple array as a linked list.

[2020 Day *][C99] Computers are fast: AoC 2020 in < 2s, including compile time
Day 23 part 2 (1 million cups, 10 million moves) runs in 0.06 s on my 2013 dual core Haswell i5 1.3 GHz. Main reason is a super fast simulated linked list via a pre-allocated array of integers. Source https://github.com/ednl/aoc2020/blob/main/day23.c

Thanks to /u/thomasahle for encouraging me to implement axial coordinates, which made it a lot easier. Also thought of a better way to parse the input in one go. And this allowed me to tighten up the grid dimensions. Runs in under a second on a very old laptop, half of which is because of the scipy import ... https://github.com/ednl/aoc2020/blob/main/day24alt2.py
