Code for the 2021 exercises at https://adventofcode.com/2021/
Some interesting things that happened on specific days:
- Day 08: 7-segment digit reconstruction.
- Day 10: delimiter matching.
- Day 12: depth-first search.
- Day 13: origami!
- Day 15: uniform-cost search (Dijkstra); puzzle B code pending - the grid is too big, we need to support different underlying structs in sqrid.
- Day 16: binary parsing using nom.
- Day 17: discrete parabolic trajectories.
- Day 19: linear transformations using matrices - and an actual list of all valid linear rotational matrices.
- Day 22: positive and negative area cuboids - reminds me of firewall rule analysis.
- Day 24: used rayon for parallelism and dashset for cache to get a viable brute-force performance.
