$($b$)$ Rewrite your assembly language equivalent of the code above using the stack to pass parameters and handle the return value. Make sure that you populate register C with the return value that is passed via the stack. $(10\%)$

;Push the values of registers A and B onto the stack

PUSH A

PUSH B

;Call the sum subroutine

CALL sum

; Pop the return value from the stack into register C

POP C

; Halt the program

HLT

; sum subroutine

sum:

; Pop the values of registers A and B from the stack

POP B

POP A

; Add the values in registers A and B and store the result in register C

ADD C$,$ A$,$ B

; Return from the subroutine
