Consider the following code fragment:

int j;

void foo(int f) {
  int j;
  j = f + 1;
  print(j); /* print-1 */
  bar()
}

  
void bar() {
  j = 20;
}

main() {
  j = 10;
  foo(10);
  print(j); /* print-2 */
}
  
(i) What values will be printed out when using static scoping? [3 points]





(ii) What values will be printed out when using dynamic scoping? [3 points]




(iii) Let's suppose we rewrite bar as:
         void bar() {
            int j;
            j = 20;
         }
      What values will be printed out when using static scoping and dynamic
      scoping? Explain why these values are the same or differ from the values
      in (i) and (ii) [4 points]
