Question $4(20\%)$: Write an Assembly program that is composed of the following

procedures$/$subroutines and instructions

a$.$ A Compute procedure that takes a variable, called $n,$ and computes the

following equation:

$A={\displaystyle \underset{i=0}{\overset{n}{}}}(2^i-5)$

You need to use LOOP to compute $A.$ You are not allowed to use the MUL

instruction to implement this function. Instead, you need to use the SHL

instructions.

b$.$ In the main procedure, add the necessary instructions and memory allocations

to call the Compute procedure. In particular, the variables $n$ and A should be

declared in the data segment without initialization. The main function should

set the value of $n$ to $13$ and compute the value of $A$ by calling the Compute

function. You need to ensure that the result is correct.

Hent: after running the code, the variable A should store the decimal value of $16313.$
