Program 2: Write a MIPS program that will ask the user for a negative integer (we will call this n ), check if it is negative, if not throw an error. Iteratively calculate the factorial ofn squared (n2). Assume n is between 0 and -5, there are some issues with factorial calculations with big numbers which we will discuss in class... don't sign yourself up for those). Recursion is a problem for future assignments, so do this iteratively
