Consider the following pseudo code: What does this program print when main is executed if the language uses static scoping? What does it print with dynamic scoping? Why?

var x: Int // global variable def set_x(n: Int) print_x ) f println(x) def def first ) set_x(1) print x() def second () var x: Int set x(2) print_x() def main () f set_x(0) first() print_x() second() print_x)
