advent-2021 VS advent-of-code

I wrote this script ( https://github.com/jstanley0/advent-2021/blob/main/22.scad.rb ) to translate the problem input into input for OpenSCAD, where I rendered the STL and sliced it in Cura. The tree supports are were added by the slicer and are not part of the actual shape, which doesn't lend itself well to printing without support.

For a full write-up, see this repo, and for a non-annotated solution, see:

Otherwise, the main way I solved this was with a flat list of tokens rather than a truly nested structure. This was very similar to last year's Day 18, which I also solved in a similar manner.

Code can be found in this repo.

First 2D one! Got to reuse my InfiniteGrid class, which made this much easier.

Mine only took about 2 minutes when I originally recorded it. I've since added some optimizations to my Intcode computer, and re-running my original program with the optimized computer now runs in about 45 seconds. 😁

Here is my solution in JS, which also has a long comment explaining the main iterative loop.

Your solution is very similar to mine, and I too found that using an Array of a set size was way faster than an ordinary Object. I believe it has to resizing the array / object.

Main code for part two here, with comments, and full code for all parts found here.
