Here are my solutions for the Advent of Code 2021 Challenge. Solutions are to be provided in Go and Rust1.
I will attempt to write as elegant and performant a solution as possible2 in both languages. Is it possible to solve every puzzle in under a second? All language features are on the table.
1. I have never used Rust at the time of writing, but feel this is a perfect opportunity to learn
2. I don't profess to being an expert in any of these languages
To build and run Go solutions:
cd go && make
./bin/aoc-2021 --benchmarkTo build and run Rust solutions:
cd rust/aoc
cargo +nightly run --bin benchmark --releaseAll puzzles were benchmarked on the following laptop:
macOS Big Sur (11.5.2)
MacBook Pro (2019)
2.3 GHz 8-Core Intel Core i9
16 GB 2667 MHz DDR4
