Initial version of the code tried to solve pt 1 using BFS, which took way too long even for the test data. After some fiddling with algebra with pen and paper, I realized this 2 formulaes (using first example): 94 * b1 + 22 * b2 == 840 34 * b1 + 67 * b2 == 540 *b1 = button A presses *b2 = button B presses ... could be rewritten to this single expression: (94 + 34) * b1 + (22 + 67) * b2 = 840 * 540 I failed to remember the algebra for solving x than y though, that I had to learn from the subreddit. In the code, this is the ratio part. Also, this solution using fractions is SICK. https://www.reddit.com/r/adventofcode/comments/1hd4wda/comment/m1tz3nf/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button |

Advent of Code 2024
Solutions for #aoc2024 in Python 3 (3.12.7).
Programming setup:
- Lenovo Thinkpad X260
- Arch Linux with Hyprland
- Zed editor (Ruff, Pyright)
- Firefox
- 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> new
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
