Determine the output of the following program by constructing a box trace:

public class ThisExample {

public static void main(String[] args) {

System.out.println(getValue(1, 7, 7));

}

public static int getValue(int a, int b, int n)

{

int returnValue;

System.out.println("Enter: a = " + a + " b = " + b);

int c = (a + b)/2;

if (c * c <= n)

returnValue = c;

else

returnValue = getValue(a, c-1, n);

System.out.println("Leave: a = " + a + " b = " + b);

return returnValue;

}

}
