Consider this code:

public static void displayArray3(int [] array, int first, int last)
    if (first == last)
        System.out.printin(array[first] + " ");
    else
    {
        int mid = (first + last) / 2; //consider first + (last-first) /2
        displayArray3 (array, first, mid);
        displayArray3 (array, mid + 1, last);
    }
}
                        

An initial call to displayArray3 has parameter values of 0 and 20 for first and last respectively: displayArray3(myArray, 0, 20).
Which of the following would be the values of first and last in the second recursive call from that method call?

• 10,20
• 0,10
• 0,20
