Lost 60 minutes due to misinterpreting this in p2: > *whenever* you generate a hash The code initially only did the 2016 stretching for the triplet hash, not the quintet hash. By doing it to both, pt 2 is solved. Not sure the lru cache actually speeds anything up. Many on the subreddit used the approach to generate the quintet first and look backwards 1000 times for a matching quintet (since quintets are more rare than triplets), this will most likely speed things up. Also, this solution do not store the found keys. Many other solutions do, I believe this is some presumptions. |

Advent of Code 2016
Solutions for #aoc2016 in Python 3 (3.12.7).
Setup
Since I want to remember, this is what was used to solve the puzzles.
- Lenovo Thinkpad x260 laptop with Arch Linux.
- Hyprland with gBar.
- Editor: Zed.
- Terminal: Alacritty.
Help scripts
Display all solved puzzles:
python aoc.py
To bootstrap a new puzzle (creates input/<day_no>.txt and output/day_<day_no>.py):
python aoc.py <day_no> <puzzle_name>
Manually copy the puzzle input from https://adventofcode.com and paste it in input/<day_no>.txt
to start coding.
wl-paste > input/<day_no>.txt
Solve separate puzzle (replace XX with the puzzle number):
python -m output.day_XX
Solve separate puzzle using stdin (replace XX with the puzzle number):
wl-paste | python -m output.day_XX
cat tmpfile | python -m output.day_XX
Execute separate puzzle on file save (replace XX with the puzzle number):
ls output/*.py | entr -c -s 'wlpaste | python -m output.day_XX'
ls output/*.py | entr -c -s 'cat tmpfile | python -m output.day_XX'
ls output/*.py | entr -c -r python -m output.day_XX
(requires entr and wl-paste, Mac users can instead use pbpaste. If you
prefer X at Linux, use xclip -selection clipboard -o).
To lint files:
ls output/*.py | entr -r -c flake8 output --ignore=E741,E501,E203
