Solutions to 2021 and 2022 Advent of code.

Summary

Advent of Code is an annual advent-calendar of programming puzzles. Here are my solutions in Golang.

Running the Code

To fetch the input, and create a template dir for each day:

./new_day {2022} {day1}

To then run the solutions:

// using 2022 day1 as an example
cd 2022/day01

// run the binary
go run main.go

// run tests
go test

// benchmark solution
go test --bench=BenchmarkMain

Runtimes

The results are found using a BenchmarkMain benchmark in each solution. This table is generated by running the benchmark.sh script.
