$3\mathrm{.}14$ Consider the following pseudocode:

x : integer $--$ global

procedure set$\_$x$($n : integer$)$

$x$:$=n$

procedure print$\_$x$()$

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

procedure first$()$

set$\_$x$(1)$

print$\_$x$()$

procedure second$()$

$x$ : integer

set$\_$x$(2)$

print$\_$x$()$

set$\_$x$(0)$

first $()$

print$\_$x$()$

second$()$

print$\_$x$()$

What does this program print if the language uses static scoping? What does it print

with dynamic scoping? Why?
