Advent Of Code

In this repo I'll update my solutions to the yearly challenge of Advent Of Code by Eric Wastl.

Languages

Python

I chose Python because it's flexibility allows me to try different aproaches quickly. It's is my go-to language when I've to prototype and iterate.

Crystal

Crystal is almost as easy to write as Python and runs almost as fast as C. It may be a young language but it's a lot of fun to write!

Julia

Julia is a really powerful language. It may not have Python's scripting features but in my opinion it's a much better option for anything computationally intensive.

Rust

Rust is amazing. I refuse to elaborate.

Project Structure

The solutions will be separated by year and day. The input will be placed next to the sources and binaries will be placed in a build folder. Both the input and the binaries will be git-ignored.

Example:

• 2020
  • day-1
    • build
      • rust
      • crystal
    • python.py
    • rust.rs
    • crystal.cr
    • input
  • day-2
    • build
      • rust
    • python.py
    • rust.rs
    • julia.jl
    • input
• 2021
  • day-1

Benchmarks

I like to benchmark my solutions with sharkdp's Hyperfine. Here's an example of what it looks like:

hyperfine --warmup 10 -m 1500 'python3.9 python.py' './build/crystal' './build/rust' --export-markdown build/day-2-report.md

Command	Mean [ms]	Min [ms]	Max [ms]	Relative
python3.9 python.py	16.3 ± 3.8	9.5	22.0	19.37 ± 9.18
./build/crystal	1.2 ± 0.1	0.9	2.1	1.38 ± 0.58
./build/rust	0.8 ± 0.3	0.3	4.1	1.00
