Here's an example implementation in Rust, using rayon's parallel iterators to automatically distribute the computation of a range of hashes over all available cores. It solves both parts together in around 3 seconds on my M2 MacBook Pro. Single-threaded, it takes around 25s in Rust and 35s in Python.

I love doing optimizations like this but I don't really have enough time anymore to really do it. In 2020 I spent a fair amount of time writing super optimized solutions for the first 10 or so days (repo solving all those days together in 150us i.e. <1ms) but even back then, I eventually stopped since I had other things to do and it took more and more time as the days went on.

Python 3 116/125

Wow, my final solution looks almost exactly the same. Though I calculated my initial answers by hand.

That's certainly not necessary though and really not what makes most of the speed, especially for problems like today's. I don't really look at other leaderboard competitor's solutions much but at least my solutions (ranked ~20 today) are almost always completely vanilla Python (the only exception is networkx for the occasional graph problem but even that isn't really that much of a speedup if you know the common graph algorithms) and always self-contained.

Interesting approach. I guess mine could be considered a bit nicer, doing it recursively and returning the number to add to the left or right.

My priority Q/heap Dijkstra in Python runs just fine. I don't remember and can't check rn if it was instant or took a second but it definitely wasn't longer than that.

The only code differs for two parts is as follows - https://github.com/bhosale-ajay/adventofcode/blob/master/2023/ts/D07.test.ts - under 80 lines.

Easy day TypeScript, P1 - Brute Force, P2 - Formula

[LANGUAGE: TypeScript] Github - Under 40 lines, all parts running under 8ms.

[LANGUAGE: TypeScript] TypeScript - Running under 30ms (both parts)

F# This year I solved puzzles using TypeScript as well as F# - Day 18, 19, and 22 TBD

F# - After looking at some Python solution calculated the position of blizzard for nth time instead of maintaining the grid, which makes it easier with F#.
