Advent of Code solutions implemented in the C programming language with the C23 standard in mind.

The solutions themselves are located in the challenges/ directory under the respective year.
They have a suffix of either a or b relative to the part of the challenge being solved.

• cmake >= 3.21
• gcc >= 15 or equivalent for C23
• sh

The uthash header only library is included as well.
It's fetched and made available during configure time through CMake's FetchContent module.

Build all of the challenges:

$ cmake -S . -DENABLE_TEST=ON -B build && cmake --build build

The ENABLE_TEST CMake variable enables the ctest test cases for each of the challenges.

To run a specific challenge:

(build) $  ctest -V -L <YYYY> -R <DAY><PART>

Make sure to replace <YYYY> and <DAY><PART>, respectively, with the desired year and challenge day along with the part suffix (a or b), e.g. 1a.

To change the test cases' inputs, modify them in the inputs/<YYYY>/ directory.
