Consider the following pseudocode:
x : integer := 1
y : integer := 2
procedure add()
    x := x + y
procedure second(P : procedure)
    x : integer := 2
    P()
procedure first
    y : integer := 3
    second(add)
first()
write integer(x)

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

(b) What does it print if the language uses dynamic scopingwith deep binding?

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