Advent of code 2021

Here are my solutions to the Advent of Code 2021 puzzles.

Structure of the repo:

input contains the input files (not included in the repo)
raw contains the exact Python code I had when I got the second star for that day, without any type hints, comments, and possibly even without sense (but it works). If there's just a single part1.py file for a given day, it will actually contain both parts.
python contains much more readable solutions with type hints and comments using Python 3.10
javascript contains solutions in JavaScript
kotlin contains my attempts to solve the puzzles in Kotlin. I've only started learning Kotlin this month, so any suggestions for improvements are welcome.
elm contains my solutions in Elm (see the instructions inside)
