Implement 2SAT algorithm Here are some good problems to test the algorithm against: https://open.kattis.com/problems/blackvienna https://open.kattis.com/problems/pieceittogether https://open.kattis.com/problems/palindromicdna

Add algorithm to do the intersection of a line in general form (ax + by + cz + d = 0) with a sphere of radius r centered at some...

Modpow function in Mathematics folder is broken. In particular, the function fails for some negative exponents. To debug comparing against the BigInteger ModPow method is a good place to start.

See [here](https://kynd.github.io/p5sketches/drawings.html) for a nice demo. In the actual implementation consider using the barometric coordinate system.
