Advent of Code 2022

All my Advent of Code repos:

• AoC 2015 in Nim, Python
• AoC 2016 in Python, Clojure
• AoC 2017 in Nim, OCaml, Python
• AoC 2018 in Nim, Python, Racket
• AoC 2019 in OCaml, Python

• AoC 2023 in Clojure

 

Last year's Python was fun, so I'll keep it as my main language this year.

But to keep things interesting and (too?) challenging, I'll make my first learning steps in Clojure. If you have any advice how to improve my Clojure solutions, please open an issue or comment in any other way.

Solutions

Task	Python Solution	Clojure Solution	Comment for Python solution
Day 00: Helper file	aoc.py	aoc.clj	Utilities I use to solve the tasks.
Day 01	day01.py	day01.clj	Unexpected double-newline input for the first task.
Day 02	day02.py	day02.clj	Using match statement (Python 3.10+).
Day 03	day03.py	day03.clj	I like my Clojure solution more.
Day 04	day04.py	day04.clj	Look ma, no sets!
Day 05	day05.py	day05.clj	Parsing the input like a real man.
Day 06	day06.py	day06.clj	The easiest one so far.
Day 07	day07.py	day07.clj	The toughest one so far.
Day 08	day08.py	day08.clj	Look pa, no dicts!
Day 09	day09.py	day09.clj	Complex numbers --> simple solution.
Day 10	day10.py	day10.clj	Advent of off-by-one errors.
Day 11	day11.py	day11.clj	Classy monkeys.
Day 12	day12.py	day12.clj	Start from the end, obviously.
Day 13	day13.py	day13.clj	eval + pattern matching on types.
Day 14	day14.py	day14.clj	Both parts in one go.
Day 15	day15.py	day15.clj	Scan row-by-row for a hole in the scanned positions.
Day 16	day16.py	day16.clj	Floyd-Warshall and only traverse through the valves with positive flow.
Day 17	day17.py	day17.clj	The traditional "find a cycle" task.
Day 18	day18.py	day18.clj	Cubes are just points in 3D.
Day 19	day19.py	day19.clj	Ungh.
Day 20	day20.py	day20.clj	The traditional "just use deque.rotate" task.
Day 21	day21.py	day21.clj	DFS and binary search.
Day 22	day22.py	day22.clj	Hardcoded the wrapping rules for my input. Sorry, not sorry.
Day 23	day23.py	day23.clj	More complex numbers. Plain numbers are much faster.
Day 24	day24.py	day24.clj	Set operations for the win.
Day 25	day25.py	day25.clj	+/- 2 for an easy conversion.
