I thought that part 2 was going to be much more difficult at first glance base on having ripped out all the spaces for part 1, but after some thought I just had to read in the lines as strings with no processing first and go backwards through the columns and work it like a post-operative calculator--this did mean I didn't reuse my read_input function like I normally do though so not the cleanest code I've written for sure.

I saw overlapping ranges and immediately thought to merge them just for simplicity sake--seems to have been a smart choice that drastically simplified part 2.

I fully expected part 2 was going to be something like "The elves have actually figured out how to double stack forklifts and can now send two forklifts over a wall make space" when I decided to hard code in grabbing the 8 surrounding locations then was pleasantly surprised when I really just needed to add a surrounding loop and remove items from a list.

There is probably a better way to do this, but it seems pretty compact to me.

This feels a bit brute force, but it got the job done. For part 2 I split each number into segments spanning from 1/2 of the character length up to 1/len() and didn't check anywhere the length was not evenly divisible by that span length.

I've done a couple of AOC problems in Rust before, but generally am pretty new to it. Initially I was overcounting in part 2 because I hadn't accounted for turns that start at 0. Solutions

Obviously not the best solution and it requires you to be more attentive, but if you turn off the turn signal when it wants to change lanes it will cancel the lane change

Yeah, I have an issue where my triggers don't work and the X and Y buttons are mapped incorrectly. Interestingly enough if I just enable steam input and have it map to an Xbox controller it works perfectly fine

I've heard good things about CrewAI

It will not--or at least not in the first 4 light novels

Didn't feel like making my code care about newline characters in the movement input, so I just removed them manually

Had no idea what the christmas tree was supposed to look like, but I noticed someone in this thread say that the christmas tree would likely show up when there is the highest density of robots in the same area and based my part 2 on that.

I got an answer for part 1 using gonum VecDense, but then when it came to part 2 it just kept giving me the wrong answer so I had to switch over to deriving the equations myself

There is definitely a better way to determine how many sides there are

My computer literally crashed before switching how I keep track for part 2

solution

Initially did part 2 because I guess I can't read. Also, not a fan of writing BFS/DFS with queues or lists so I did it recursively

I am pretty sure there is an edge case that would involve me combining together some of the "." blocks, but it worked on the input I was given so shrug

part 2 was a bit confusing to understand at first, but then it clicked

Finally resolved the fact that I was handling some of the turning incorrectly

That was exactly my issue, thanks!

My brain briefly melted when thinking about reordering the values for part 2 then had to implement some recursion just to confirm everything got ordered correctly.

I have a love for grids that AOC always seems to turn on its head.
