Advent of Code 2024

Utilities

• Picat: aoc_utils.pi, aoc_utils_regex.pi (utilities using my regex module)
• Racket: aoc_utils.rkt
• ngn-k: u.k

Solutions

• Day 1: 1.pi (Picat), 1.rkt (Racket), 1.k (ngn-k)
• Day 2: 2.pi (Picat), 2.rkt (Racket), 2.k (ngn-k)
• Day 3: 3.pi (Picat, using my regex module), 3b.pi (Picat, a little neater version of part2), 3c.pi (Picat, better version of part 2, and another version of part 1)
• Day 4: 4.pi (Picat), 4.rkt (Racket)
• Day 5: 5.pi (Picat), 5_part2.pi (Picat, quite faster part 2 using topological sort) 5_part1.rkt (Racket, Part 1), (5_part2_rosette.rkt (Racket, Part 2, but unfortunately too slow))
• Day 6: 6_part1.pi (Picat, part 1) 6_part2.pi (Picat, part 2)
• Day 7: 7.pi (Picat)
• Day 8: 8.pi (Picat)
• Day 9: 9.pi (Picat)
• Day 10: 10.pi (Picat)
• Day 11: 11.pi (Picat, both part 1 and part 2) 11_part1.pi (Picat, brute force for part 1)
• Day 12: 12_part1.pi (Picat, part 1) 12_part1b.pi (Picat, part 1, shorter and faster than 12_part1.pi)
• Day 13: Picat: 13.pi (Picat) 13_nondet.pi (Picat, just for fun: solving part 1 with between/3 non-deterministic predicate) 13_regex.pi (Picat, parsing with the regex module ) 13_dcg.pi (Picat, parsing with DCGs)
  Racket: 13.rkt (Racket with Rosette Z3 solver) 13_matrix.rkt (Racket, using math/matrix-solve)
• Day 14: 14.pi (Picat) 14b.pi (Picat, some faster versions and alternative pattern detection methods)
• Day 15: 15_part1.pi (Picat, only part 1)
• Day 16: 16_part1.pi (Picat, only part 1)
• Day 17: 17_part1.pi (Picat, only part 1)
• Day 18: 18.pi (Picat)
• Day 19: 19.pi (Picat)
• Day 20: -
• Day 21: 21.pi (Picat, only part 1)
• Day 22: 22.pi (Picat)
• Day 23: 23.pi (Picat)
• Day 24: 24_part1.pi (Picat, part 1) 24_part1b.pi (Picat, part 1, alternative approach)
• Day 25: 25.pi (Picat, only part 1 this day)
