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 of n*n*n*n (n^4). Assume n is between 0 and -5, there are some issues with factorial calculations with big numbers which we will discuss in class dont sign yourself up for those). Recursion is a problem for future assignments, so do this iteratively.
