Advent of Code 2023

Not really going for points here, just for fun :).

I'll probably try to vary languages a bit to get some variety.

Notes

• I try not to use regex if I can help it (regex kinda takes the fun out of it and is harder to optimise if you are actually going for performance).
• Solutions are tidied up a bit, but not a lot. So this is definitely nowhere close being elegant code in a lot of cases.

Solutions

Day 1

Language: Python 3.12 (generics used)

Day 2

Language: Python 3

Day 3

Language: TypeScript (Deno)

Note: This one was re-written because what I initially wrote belongs on r/programminghorror.

Day 4

Language: Golang

Day 5

Language: Kotlin

Note: Here begin the optimisations! (some people got away with brute force, I decided not to even go there).
