Advent of Code 2019

Solutions for the 2019 Advent of Code

Building

This project makes use of Go 1.13.

go mod download
go test ./...

Running the Solutions

To run a solution, use the problem name followed by the path to an input file.

For example, to run problem 2a:

$ go run ./main.go 2a ./day2/input.txt
Answer: 9633
Took 999.4µs

Adding New Solutions

A generator program is included in gen/problem.go that makes templates for each day. For example, go run gen/problem.go 9 a will generate the following files:

• challenge/day9/a.go: The main problem implementation, containing a cobra command A and the implementation func a(*challenge.Input) int
• challenge/day9/a_test.go: A basic test template
• challenge/day9/input.txt: The challenge input

I don't yet have a way to register the cobra command in main.go automatically.
