Answer the following subprogram implementation related questions considering the below given program.
public class AR {
public static void main(String[] args) {
boolean result = isEven(3);
System.out.println(result);
}
public static boolean isEven(int n) {
boolean ie;
if(n == 0) ie = true;
else ie = isOdd(n-1);
return ie;
}
public static boolean isOdd(int m) {
boolean io;
if(m == 0) io = false;
else io = isEven(m-1);
return io;
}
}
a. [5 pts] Draw the Activation Record (AR) data structure for the subprogram isEven.
b. [15 pts] Draw the evolution of call stack (runtime stack) for the program and print the output. You are expected to show the steps of program execution progress by using activation record instances (ARIs) on the runtime stack.
