Question 4. Given the following Java program

public class Example
{
static int n = 3;
public static void main(String[] args) {
int k;
k = n;
Controller control = new Controller(k);

control.compute();
}
}
class Controller
{
int n;
Controller(int n) {this.n = n;}
void compute() {
int i, m;
int sum = 0;
String message;
Functor func;
for(i = n; i > 0; i--) {
func = new Functor();
m = func.calculate(i);
sum = sum + m;
}
message = “The sum of factorials from 1 to “ + n + “ is “ + sum;
System.out.println(message);
}
}
class Functor
{
int calculate(int n) {
int temp;
temp = n – 1;

if (n > 0) { return n * calculate(temp); }
else {return 1;}
}
}

*List all static variables, stack-dynamic variables, explicit heap-dynamic variables, and
implicit heap-dynamic variables.
