Solutions for Advent of Code

Got thrown of big time at pt 1 since there is a duplicate test value in my puzzle input. The code initially asumed that all test values should be distinct. Biased from seeing "test" in the termology, most likely. Earlier editions of the code also tried to create all combinations using binary strings, but it fell short on pt 2 when a third operation was introduced. From some inspiration in the solutions mega thread on Reddit, the final code is queue-based instead. Apparently, I also learned this kind of problem is usually well suited for DFS search, and apparently the final code very much is _in deed_ a DFS. |

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.
