Assignment $4$ for Computer Architecture

You are to write a program in MIPS that computes N$!$ using a loop. Remember N$!$ is the product of all

the numbers from $1$ to N inclusive, that is $1$ x $2$ x $3$ x $($N $1)$ x N$.$ It is defined as $1$ for N $=0$ and is

undefined for values less than $0.$

The program first requests the user to input the value of N $($display a prompt first so the user knows

what to do$).$ If the input value is less than $0,$ the program is to display $$N$!$ undefined for values less than

$0$ and request input again. If the value input is non$-$negative, it is to compute N$!$ using a loop.

You are to have your name, the assignment number, and a brief description of the program in

comments at the top of your program. Since this is an assembly language program, I expect to see

comments on almost every line of code in the program. Also make the code neat $($line up the

commands and comments in nice columns$)$ if you want full credit $($see page $134$ in your text for a nice

example$)$
