Assume two processes are modifying a shared variable in memory $($call it $x)$ as shown below.

Assuming the initial value of $x$ is $4,$ answer the following two questions.

What value will $x$ hold after both process finish execution, given that $S$ was initialized to $2.$

$($a$)3$

$($b$)4$

$($c$)5$

$($d$)$ Any of the above

$($e$)$ Cannot be determined
