AoC2015: Advent of Code 2015 C++ Solutions

My C++ solutions to the very first Advent of Code 2015 (i.e., AoC2015) some years too late.

When working on my solutions, I strive to make them as general as possible, that is, they could be adapted to solve similar problems. Elegance, readability, and efficiency, in this order, are also my concerns, though secondary after generality.

Dependencies

Install the following libraries, if needed:

• libcrypto and libssl: used to compute the MD5 hash function in day four.

Building

Use make to build the program; the executable file advent will be located in the bin directory. To clean the output directories, use make clean.

Usage

The general usage of advent, for a particular DAY, is

• advent DAY

Additionally, if you have another input for a particular day stored in the inputs’ folder, name it in the format dayDAY.EXT.txt, where EXT is any arbitrary extension. To use it, append EXT to the end of the command, like this:

• advent DAY EXT
