Solutions for Advent of Code

First part was solved using a list to store stones, since I misinterpreted this paragraph: > No matter how the stones change, their order is > preserved, and they stay on their perfectly > straight line. But since the puzzle question do not require the stones in the correct order, a list (or an OrderedDict) is not required. The pt 1 solution code got killed for eating all RAM, so valuable minutes was lost trying to create a generator instead. It failed. When searching for clues, I ran across multiple people instead utilizing dicts to count occourences. "but what of the order?", I asked, and realized only the counts was relevant. |

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.
