Implement the following expression in assembly language:

ECX $=($val$3-$ val$1)+(-$val$4+$ val$2)+3$

$-$ Assume that val$1$ is $16-$bit variable, val$2$ is $32-$bit variable, val$3$ is $8-$bit variable, and

val$4$ is $8-$bit variable.

$-$ You need to implement the expression the way it is provided, you cannot do any reduction on the

expression while implementing it$.$

$-$ Initialize val$1$ with $12($decimal$),$ val$2$ with $9($decimal$),$ val$3$ with $2($decimal$),$ val$4$ with

$20($decimal$),$

$-$ You are NOT allowed to update the values stored in val$1,$ val$2,$ val$3$ and val$4$

$-$ Use mov, add, sub, movsx, movzx, or neg instructions whenever needed.

$-$ Use the debugger to verify your answer.
