This year I'm going to use Golang to solve the puzzles.
To run a particular solution, for example day 1, use the following command:
go run cmd/day01/main.goThe last column contains improved solutions inspired by solutions of other people.

The documentation for the standard library can be viewed using godoc.
First, install the godoc tool:
go install golang.org/x/tools/cmd/godoc@latestNext, run the following command to start the documentation server:
godoc -http=:6060Finally, open a browser with the following URL: http://localhost:6060/.
If the godoc binary cannot be found, make sure to add $GOPATH/bin to $PATH:
export PATH="$PATH:$(go env GOPATH)/bin"
