1 Problem 1 - Lexical/Dynamic Scoping This problem uses the following progranm int var; //global variable procedure set.var (int val): var := var; procedure output.var (): print var procedure foo () set var (2) output.var (); procedure bar() int var; set var (4) output var ); set var () foo ( output.var (); bar output.var () (a) Suppose this program uses static (lexical) scoping. What will it print, and why? (b) Suppose this program uses dynamic scoping. What wl it print, and why
