My attemt at Advent of Code 2021 using Go

Advent of Code 2021 via Go

This repo contains my attempt at Advent of Code 2021 (https://adventofcode.com/2021).

Running it

• Install Go 1.17 (or higher)

• Run the go run CLI inside the package you wish to run. For day 1, you would run:

  $ cd cmd/day01
  $ go run .
  [INFO |common|…common.go:72] Reading file.  path=input.txt
  [INFO |day01 |…/day01.go:44] Scanning complete.  scans=2000  increases=1791

  To run part 2 of the puzzle, add the -2 flag:

  $ cd cmd/day01
  $ go run . -2
  [INFO |common|…common.go:72] Reading file.  path=input.txt
  [INFO |day01 |…/day01.go:22] Using windowed scanner.  window=3
  [INFO |day01 |…/day01.go:44] Scanning complete.  scans=1998  increases=1822
