Anders Englöf Ytterström cbd4bf50e1 Solve 2023:04 "Scratchcards"
On a train that according to swedish tradition
was late. Not a good environment to focus.

Got stuck 2 times:

- Initial code asumed the | was always after the 5th
  number, because of the example. Puzzle input had
  it at pos 10. Classic AoC mistake.
- I had a hard time trying to understand the score
  count, I insisted there was meant to be a +1 at
  some point.

  > That means card 1 is worth 8 points (1 for
  > the first match, then doubled three times for
  > each of the three matches after the first)

I should instead have just looked at the numbers.

Solutions for #aoc2023 in Python 3 (3.11.5).

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 'xclip -selection clipboard -o | 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).
