Using the pseudo$-$code below answer the following questions: $($Assume all parent processes wait for their children

before ending$).$

p$1=$ fork$()$

p$2=$fork$()$

if$($p$1>0)$

$\{$

exec$(....)$

$\}$

$($enter number only$)$

What were the maximum processes $($before exec..$)$ that have p$1>0?$

What were the maximum processes $($before exec..$)$ that have a p$3=$ to $0?$

How many processes will exec?
