An implementation of the Advent of Code for 2020.
There is an application in the root directory for running the scenarios. The -a flag is used to select a scenario in the range of 1 to 25. The application reads from standard input for test data, copies of which are provided in subdirectories.
From the root you can run a scenario using go run main.go -a SCENARIO <DIRECTORY/input.txt. For example, to run the third scenario, use go run main.go -a 3 <advent03/input.txt.
There are a few unit tests in some packages. They can be run with go test PACKAGE_PATH, E.g. go test github.com/igilham/aoc2020go/advent04.
