    Advent of Code (by ednl)

    C has no intersection operation, so I sorted the numbers and counted the matches "manually". Only kept an array for the number of card copies and could do the rest while reading the input. Runs in 3.2 ms on an old 2013 iMac, 3.9 ms on a Raspberry Pi 4 (cpu governor = performance). Short code, only one separate function for sorting: https://github.com/ednl/adventofcode/blob/main/2023/04.c
