🎄 Advent of Code 2020 in Go 🎄

These are my attempts at Advent-of-Code 2020 in Go. Benchmarks, tests and improvements will be added over time for each day.

Benchmarks

Benchmarks have been included to test the initial input file parsing to []string, and the part 1 and 2 function for each day. Quoted benchmark times are from a laptop (i7-10510U). Benchmarks can be run for any day from the base directory:

$ go test ./day10_adapter_array -bench=.

Tests

Tests related to the specific input.txt can be run for each day from the base directory:

$ go test ./day10_adapter_array
