Initial tries to use a while loop instead of
recursion gave a classic AoC situation: test cases
worked, but not actual AoC puzzle input.
Turns out I only considererd removing the longest
pattern form the design, rather than consider all
possible removals.
Some Python goodies in here:
- `"abcdefgh".startswith("abc")` instead of regexp.
- removeprefix() is nice, and in some cases more
readable. `"abcdefgh".removeprefix("abc")` vs
`"abcdefgh[3:]"
- To speed things up for pt 2, functools is used
which requires a dict to be hashed as a tuple.
If one wish to solve this without recursion, a
BFS solution is most likely the way to go.
def ispossible(design, patterns):
Q = [design]
possible = 0
while Q:
remaining = Q.pop(0)
if not remaining:
possible += 1
continue
for pattern in patterns[remaining[0]]:
if remaining.startswith(pattern):
Q.append(remaining.removeprefix(pattern))
return possible

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
