This year, for my 4th Advent of Code, I have decided to use Go, to learn the language. This is my first ever time using it.
For all problems, I used Go 1.21.3, installed using gobrew.
To build the executable for a given day, run go build -o ./bin ./cmd/dayXY from the root of the project. This will output the binary in a bin subdirectory. Then, this program can be run by redirecting the input from the appropriate file under inputs (all programs expect input on stdin).
Alternatively, to execute the program for a given day directly, run go run ./cmd/dayXY < inputs/dayXY > output to obtain the output in a file.
