Advent of code 2023

Here’s my solution for day 12. Main highlights:

  • Takes about 2.2 seconds in total to solve both parts. Then just 0.03 seconds on a subsequent run, due to tabling.
  • Tabling requires the lists to be ground, so I used u instead of leaving list elements var
  • Neat example of using a DCG for file import
