🎄 Advent of Code 2023 🎄

Summary

Advent of Code is an annual Advent calendar of programming puzzles. This year I am doing it in Python.

Running the code

To run the code of a specific day from the root directory run the following, replacing xx with the day number, 01 - 25. Make sure you use Python 3.10+.

python3 day_xx/main.py

You may want to replace python3 with your version of python (eg. python3.13) if the command above doesn't work.

To run the code of all days run the script:

./run_all.sh

Make sure you have given permission to execute (chmod +x run_all.sh).

New Day

To generate the directory for the current day, save your browser cookie in a file called cookie.txt at the root level and run the new day script:

./new_day.sh

How to get your cookie

A session cookie is a small piece of data used to authenticate yourself to the Advent of Code web servers. It is not human-readable and might look something like this 53616c7465645f5fbd2d445187c5dc5463efb7020021c273c3d604b5946f9e87e2dc30b649f9b2235e8cd57632e415cb.
