Solutions for Advent of Code

This is how far I got the Dec 2022 run in Elixir. Had no idea what so ever for pt 2, so I had to solve it by the solutions thread in the subreddit. At first, I wondered if circular values would be the case. It was not. Apparently, modular arithmetics are what I lack knowledge about. Not entirely sure what to call the operator, it is either a greatest common divisor or a least common nominator. What it actually does is to reduce the numbers by modulo for pt 2, which will keep them low and faster to compute. My math is rusty. |

Advent of Code 2015–
Here all solved puzzles for Advent of Code are kept for reference. Most solutions are written in Python, but there are also solutions written in Elixir.
- Initial runs from 2016–2020 are squashed in version control, so the original thoughts/rants about the solution are forgotten for future generations.
- 2021 onwards, each solution will have a separate commit. This also includes revisiting old events.
Where are the puzzle input files?
For many years, this repository had all puzzle inputs under version control. They are not anymore, although the scripts asumed they are downloaded and stored locally in a subdirectory, which is ignored by version control.
The reasons:
- Neither you or me do have permission to reproduce or redistribute them, they are not released under public domain or MIT/BSD/GPL or any other license.
- The author behind advent of code have kindly asked us who attend Advent of Code to not release them, since publiced puzzle inputs cen be used to copy the site and steal the AoC creator's work.
