This repository contains my solutions to Advent of Code puzzles. I started solving them in 2020, and I'm continuing to do so in 2022, 2023, and 2024. So far, I didn't have time to solve all the puzzles in a given year, especially when work gets busy, puzzles get harder and it’s time to prepare for Christmas. Hoping this year will be different. 🤞
About Advent of Code
From the subreddit Wiki:
Advent of Code is a series of small programming puzzles for a variety of skill levels. They are self-contained and are just as appropriate for an expert who wants to stay sharp as they are for a beginner who is just learning to code. Each puzzle calls upon different skills and has two parts that build on a theme.
You can access the problems here: adventofcode.com. It will show you the most recent problems. If you want to access other year just type adventofcode.com/2019 for the year 2019.
For AoC 2024 I will solve the problems in Python (and sometimes I'll add Bash solution). Each day's solution is linked to its rendered HTML output and notebook source.
For an overview of my journey and insights, check out my blog post on AoC 2024. ✍️

For AoC 2023 I am solving them in Python, in Jupyter notebooks (run in VS Code). I don't keep the inputs, as per the request of the creator of Advent of Code. I have GitHub Copilot running in VS Code, but only use it for autocompletion, the ideas for solutions and their implementation is mine. I also use GitHub Copilot for doc strings and minor improvements after I solve the tasks.

For AoC 2022 I decided to solve the problems by writing up my solutions in Quarto Publication (so far using Python). You can look up the answers in the online version of the notebook here.
In 2020, I solved AOC 2020 challenges using R with solutions organised and split into subdirectories, you can check them out here.
