I just completed "LAN Party" - Day 23 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/23

(using a dictionary for Part 1, networkx FTW for Part 2!)

I've completed "Keypad Conundrum" - Day 21 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/21 github.com/marcodelmast... (Today was as difficult as Day 19, and in some sense similar in what the solution for part 2 needed)

I've completed "Reindeer Maze" - Day 16 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/16 github.com/marcodelmast... Dijkstra indexed on path score; for Part 2 saving full path and accumulating all positions for paths with best scores, returning total set when best score is exceeded

I just completed "Claw Contraption" - Day 13 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/13 github.com/marcodelmast... (after some pondering I realised the problem can be reduced as a system of two linear equations with two unknowns, relatively simple to solve!)

I just completed "Garden Groups" - Day 12 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/12 github.com/marcodelmast... (Part 2 was tricky: I got the idea of finding vertices by projecting the square centres pretty quickly, but to account for concave patches I needed to make drawings)

I've completed "Disk Fragmenter" - Day 9 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/9 (today I had almost no time and arrived quite late. Not difficult, but not easy. Brute force FTW as usual ;))

I've completed "Bridge Repair" - Day 7 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/7

github.com/marcodelmast...

(There might be some mathematical shortcut, but I went for the brute force solution)

I just completed "Guard Gallivant" - Day 6 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/6

(for Part 2 I initially tested all position on map to place obstacles, then realised I only need to place them on the initial path of the guard)

I've completed "Print Queue" - Day 5 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/5

Wrote a custom `compare` function, passed to sorting algorithm via `functools.cmp_to_key()`. After that, part 1 and part 2 are basically solved in the same way:
