This is a repository of my Advent of Code solutions. Some puzzles are accompanied by concise descriptions 😉

I try to optimize each solution as much as possible, so although they are written in Python, many run in less than a second!

Also check out these cool animated annual AoC images!

Some facts about this repository:

• My goal is to keep solutions as close to the original as possible, so I generally do not edit past solutions. Sometimes I correct the code style (without even remembering what the task was about), but in the future I will try not to do this

I also follow some rules for writing my solutions:

• The entire repository is PEP8 compliant, as verified by the flake8 linter (with the exception of some rules)

• Input files may contain any number of empty lines, especially at the end. In some cases, this also applies to whitespace characters.
  Currently I like to handle this rule using the following general snippet to read files:

  with open('input.txt') as file:
      lines = list(filter(None, map(str.strip, file)))

If you computer scruggles to render smooth animations, buy a new one¹ :)

Footnotes

1. Joking of course! It's just that almost all annual AoC images contain a ton of HTML objects, each with its own animation. Rendering one image on a modern hardware is easy, but when there are many of them, it becomes a mess)
   In all seriousness, I'm not sure if I want to hold on to these animations or drop some of them ↩
