Basically just a way to code the Dirichlet Convolution problems for my number theory work.
Instructions to use:
First, edit the convolution call in main to make it use the functions you want it to use. Then, compile the code. I used gcc on Arch Linux, but it should be the same for any Linux/Unix setup. Finally, execute the executable you compiled and input the number you want to convolute.
Good thing I wrote these 50 lines instead of writing 2 lines of LaTeX
