- What is the output of the following code for n = 15? n = 65 ? What does this program appear to do?

public static void mystery (int n) {

StackInterface s = new StackReferenceBased();

while ( n>0) {

s.push ( n%8);

n = n / 8;

}

while (!s.isEmpty())

System.out.print (stack.pop());

System.out.println();

} //End mystery
