Advent of Code 2021

My personal solutions to the Advent of Code 2021 challenges.

Building

To build the challenge solutions:

make

To clean the build objects:

make clean

Running

To run the challenge (either part 1 or part 2) for a specific day, the format is:

./bin/XX <1|2> < input/XX.txt

E.g. to run day 2, part 1:

./bin/02 1 < input/02.txt
