Hi, I'm mcpower. I've done Advent of Code seriously for two years now in Python, placing 9th in 2018 and 12th in 2017. This year, I'm taking a break from aiming for the leaderboard - while it's fun and all, it is a bit stressful at times (the good kind of stress, though!). As such, I'd like to share a few tips for anyone wanting to aim for the leaderboard.

This is everything that worked for me. Your mileage may vary, though - don't take this as gospel, see what works for you.

This challenge involves an old version of CS:GO VScript, which is vulnerable to a UAF bug and a type confusion bug.

UAF by resizing array in sort compare function

The sort function of squirrel array is array_sort in sqbaselib.cpp, which will call _qsort:

// v: VM, o: array object, func: compare func
