Consider the following program: { int x = 7; void p () { write (x); } void q (void px ()) { int x = 4; px (); } void r () { int x = 3; q (p); } { x = 1; P (); q (p); r (); } } What does the program print in case of (i) static scope (and deep binding), (ii) dynamic scope and deep binding, (iii) dynamic scope and shallow binding. Explain by describing how the program is executed.
