For instance, I wrote this in C for day 15 https://github.com/ednl/aoc2020/blob/main/day15.c which runs in 1.635 s on a Raspberry Pi 4 (4 GB, RPiOS 32-bit on SSD, overclocked to 1.8 GHz) when timing on the command line with "time", taking the lowest "user" value of about 10 manual runs. Compiled with gcc -Ofast (version 8.3.0).

Well done on your 0.541s timing by the way! Mind to test my day15b implementation as well on the same system? It's standalone and straightforward to run.

Interesting! I did something similar but haven't gotten further than day 13 yet (and skipped day 11 and 12 for the moment).
