Got this one ruined due to a post not masking spoilers: https://www.reddit.com/r/adventofcode/comments/1pkxibs/2025_day_25_part_1_still_pretty_clueless_why_its/ Basically, ignore the test case and just wing it by asuming the 3x3 can be placed without overlaps. Id the number of shapes * 3x3 is bigger than the available canvas, it won't fit. A naive first check to do before making premature optimizations. I would have gone the zip() hell route to prove it actually works, but after grasping at the puzzle input i realized it would tka a looong time to calculate. |

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.
