day 18 advent of code 2024

[@gbegerow]

This day I was burnt by assuming the bytes will fall one by one on every step. You never get the right answer for the tests and it will defintively not simplify the code...

yeah I also thought this was going to be the problem when I was reading it.

With binary search you only need to do 12 tests instead of 3450

I did a linear search in part2 which took about 30s. Then I realized that it could be done with binary search and ended up with 18ms.

@@aderakin5395 it's nice to have boring days interleaved with the interesting ones when the problem set lasts for an entire month
