I am having a hard time understanding the output of this program with shadow and deep binding.

Can someone explain it more in detail? I posted the answers below

x : integer global procedure set x(n : integer) x := n procedure print x() write integer(x) procedure foo(S, P : function; n : integer) x : integer := 5 if n in {1, 3} set x(n) else S(n) 174 Chapter 3 Names, Scopes, and Bindings if n in {1, 2} print x() else P set x(0); foo(set x, print x, 1); print x() set x(0); foo(set x, print x, 2); print x() set x(0); foo(set x, print x, 3); print x() set x(0); foo(set x, print x, 4); print x()

Here are the answers to the questions.

The program prints = 10 20 30 40 with shallow binding

The program prints = 10 52 00 44 with deep binding,
