Advent of Code 2024
adventofcode.com

Alright, show me I’m not the only one in this community, and show off some solutions!

Here’s my Day 1 solution in Factor (minus imports):

spoiler 
: get-input ( -- left-list right-list )
  "aoc-2024.01" "input.txt" vocab-file-lines
  [ split-words harvest ] map unzip
  [ [ string>number ] map ] bi@ ;

: part1 ( -- n )
  get-input
  [ sort ] bi@
  [ - abs ] 2map-sum ;

: part2 ( -- n )
  get-input
  histogram
  '[ dup _ at 0 or * ] map-sum ;

Sadly, Factor doesn’t get highlighted here, so here it is again as an image:

I probably won’t last the week, but what solutions I do have will be up on GitHub.
