Mine is taking ~115ms on my 9 years old i5-3340M :D

Rust - just collect in range intervals per line. Sum of lengths is basically p1 and p2 is just a loop over rows looking for one with more than one interval. Total runtime for both parts is ~650ms. twitch, youtube.

Rust. Obs crashed and I didn't notice it until the end so here are partial recordings: twitch, youtube.

It's 'cheating' only in the sens that I wanted to measure real i/o so it would be cheating in my case. And funnily enough I had a bug there that I just fixed :D

My real solution runs in 19ms and is here. The one with BigUint is on a branch here.

Simple rust solution that solves both parts with same function. Recordings twitch and youtube.

Rust / Recording

Rust with runtime ~450µs

Not a problem, but a cool feature of Java that may be useful is reflection. Like in Handler, rather than writing out all 25 if cases for the 25 days, you can just grab a class from it's name instead. Or even further, stuff like https://github.com/abnew123/aoc2022/blob/main/src/aoc2022/MasterSolver.java where you can directly execute methods.

Now, to be clear, I've only done Tier 1 kind of myself (https://github.com/abnew123/aoc2022/tree/main/src/aoc2022 has the solutions and timings, the "kind of" is since I've only solve 23 days). But I'm sure at least Tier 3 has been done by someone on the sub, and maybe Tier 4? Would be really cool seeing some millisecond level solutions on some of the longer days (and possibly a useful learning to speed up code in future years).
