AdventOfCode2021 VS AdventOfCode2019

I found this repository which solves the problem by having a src/main.rs file which basically calls cargo run --release {day} and parses the output to extract the time each day took, but I don't find this very satisfactory. I'd prefer to have everything compiled into the same executable, without having to run external commands.

You can always check out the problems from previous years.

https://adventofcode.com/2021 for practice.

Here is 2021: https://adventofcode.com/2021

The field is called "compiler design". Consider taking a course [1] or buying a book?

A somewhat more playful approach might be to complete the 2019 edition of Advent of Code [2], where you'll learn some preliminaries while implementing the Intcode interpreter.

The ending of Advent of Code 2019 was amazing. Well, the whole season was awesome, but the ending was amazing.

2019 in Rust

This is the seventh year puzzles, if you want to check out previous years take a look at: 2015, 2016, 2017, 2018, 2019, 2020

I believe this is the direct link to the mentioned challenges: https://adventofcode.com/2019

If you want to get started, I would recommend doing Advent of Code 2019 https://adventofcode.com/2019. It goes through and shows how to implement a basic VM. 0x10c / DCPU-16 is also a good place to start. Such simplified CPU-s help you get started and understand the basics without overwhelming you with the complexity :D.

Overall, I think this year felt a lot easier than the last one. Almost no graph problems, no path finding algorithms, and no insane math problems like day 22, 2019. It's really hard finding the right balance. I think 2019 was maybe a bit too hard and discouraged a lot of people. I like that this year was more approachable but perhaps it was a bit too easy towards the end.

Thanks for an amazing year! Definitely a lot easier this year than last one, which was a bit sad. No hard graph problems, requiring path finding algorithms, no insane math problems like day 22 last year. It's hard finding the right balance. I think 2019 was maybe a bit too hard and this year maybe too easy.
