Advent of Code is an Advent calendar of small programming puzzles for a variety of skill sets and skill levels that can be solved in any programming language you like. People use them as a speed contest, interview prep, company training, university coursework, practice problems, or to challenge each other.
I solve all the problems in Rust and sometimes use some other interesting languages.
- day14: define meaningful images mathematically
- day17: this is a search problem that we can solve by Dijkstra nicely
- day18: bisect
- day24: a variant of search problem with a shallow but vast search space requiring mathematical intuition or analysis
