Help regarding 2021 Day 19
You can try to read my walkthrough... You cannot just match one edge to another edge, as there may be match in magnitude but are in fact totally off. You have to test for all edges, and you'll eventually know if two scanners line up if there's more than just two 'lucky' points (i.e. edge) that exists for both scanners.

Nim with my walkthrough here. Similar to the other solutions, just brute-forcing all possible moves for Dijkstra's algorithm. My walkthrough simply explains how to figure out the valid moves to do so, turns out it isn't too hard after having written it down (and simplifying my code).

My A* in Rust only stores (position, time) as state, as you can deduce where the blizzards are after N minutes: code. This is quite expensive, though, as you need to run it for each node expansion (unless you do caching).

Python, 407/8. Part 1, Part 2, Part 2 cleaned up. How did y'all do part 1 so quick?

Python, 198/34. Part 1, part 2 is below as it's mostly self-contained.

Python, 6/3. Part 1, Part 2. The main "tricks" I used were:

Python, didn't leaderboard. Cleaned up code for part 1 and part 2.

-🎄- 2021 Day 14 Solutions -🎄-
Python, 8/28. Part 1, Part 2. My part 2 turned the input into "a Counter of adjacent pairs of characters", which you need to be careful about because turning that to "a Counter of characters" is not easy - you double-count all characters except for the first and last which cost me an incorrect submission!

its like 600 lines, I recommend writing your own so that the functions make sense for you. Here is the "library" from someone that gets on the global leaderboard (mcpower): https://github.com/mcpower/adventofcode/blob/master/2020/01/utils.py
