We are going to solve the Nintendo HireMe.cpp challenge with some "basic" math. I call it basic, because linear algebra is taught pretty early in school. But I know it is not so easy to figure out that it can be used here. Also the trick with GF2 is math that you would only learn at university. But if you would watch my videos, you would have know it from the software_update video writeup ;)
