Consider the following pseudocode:

$x$ : integer :$=3$

$y$ : integer :$=4$

procedure add

$x$:$=x+y$

write$\_$integer$($x$)$

procedure second $($P: procedure$)$

$x$ : integer :$=5$

$p()$

procedure first

$y$: integer :$=6$

second$($add$)$

first $)$

$($a$)$ What does this program print if the language uses static scoping? $(2$pt$)$

$($b$)$ What does it print if the language uses dynamic scoping with deep binding? $(1$pt$)$

$($c$)$ What does it print if the language uses dynamic scoping with shallow binding? $(1$pt$)$
