This lets you cut out the relatively expensive fcount.remove(0) operation, and each loop is basically one addition and a few assignments. Full solution here.

Code

Your solution is pretty much exactly the super concise version of my definitely over-engineered solution.

You can see the code here

Here's my solution

Your solution looks remarkably similar to my Rust solution which solves both parts in 1.6s on the cheap NUC I use as my coding workstation.

It's in Rust, so I'm not sure how readable you'll find it, but in case it helps, you can see the code here.

I found a single crate with a bunch of binaries worked well. It let me use a shared library easily. You can see my crate organization here if that's helpful.

You can see my code here in case it helps.

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.
