Advent of Code 2022

Python files read from stdin and can be run like this:

python part_one.py < input.dat

Solutions written in Haskell and other languages might have a different method of receiving a file – typically as an argument or through stdin.

Scoreboard

✔ : Finished on time
🆗 : Finished, but a little late
⭐ : Free star

Delta: Time between finishing part 1 and 2
Late: The day I finished the task, if it wasn't the day the task was given
Time: Execution time, measured with time

Languages: Python (🐍), Haskell (λ), C++ (➕)
