This years advent of code. Solved with Go just to give me a refresher on the language.
Each day is a submodule. The submodules (days) should take an io.Reader of the input
and calculate the correct result or return an error.
The main module brings all the days together and provides a basic CLI in which to execute the solutions against the real input.
Executing main.go will output the answer for the most recent solution but supports re-execution of previous days. It will also output the time taken to calculate the result.
go run main.go -h
go run main.go -d <DAY>
