aoc2020 VS advent-of-code

To be fair, compared to other years, only Elixir (last year) was more frustrating to learn than Rust (such that it does look like the picture above, due to many prototypes and all visualisation code being written in Python). I used Kotlin in 2020 and did Go for 2018 (though I didn't participate in that one live). I'm using C# this year, and all of these were simple enough that I didn't need to spend more time learning how to do things than actually doing them.

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.
