$(20$pts$)$ Write an IAS program to compute the factorial f$($n$)=$n$!$ using instructions from the Table $2$ where

the value of n is stored at the memory location OFA. After the execution of your program the output value f$($n$)$

must be stored at location OFB. For example, if the content of OFA is $4$ then a value of $24(4!)$ must be present

in memory location OFB. A snapshot of the memory is given as a table on the right. Write your code below:

Hint: $1$ added a new instruction $($MOV$)$ in Table $2$ to assign a scalar value to AC$.$ At first, think about the

pseudocode.
