The purpose of this assignment is for you to become better at comprehending x86-64 assembly language. We will not write assembly language programs. Instead, in this assignment you are given 5 functions in x86-64 assembly language. Your task is to reverse engineer these 5 functions by writing them in C. Each correct answer is worth 1 point.

Your C code does not have to compile into exactly the same .s code that I have given you. Rather, you will be graded on whether or not your C functions properly emulate the assembly language; that is, they both should return the same value provided they are passed the same values as parameters.
