Advent of Code 2024

Advent of Code 2024 started today. This is my fifth year participating. Previous years were: 2020, 2021, 2022 and 2023.

BBB = (DDD, EEE)
CCC = (ZZZ, GGG)
DDD = (DDD, DDD)
EEE = (EEE, EEE)
GGG = (GGG, GGG)
ZZZ = (ZZZ, ZZZ)

6AJT8 318
AA4QQ 125
62KK6 876
7A7QK 241
...

The left side is our card hand. The right side is our bid amount. As always, we begin with parsing. For our purposes of illustration, I'll skip the first 20 hands to get to a more interesting one with a J:
