While Loop Simulation

	Consider the following method: 

public static void mystery(int y) {
	int x = 0;
	int z = 0;
	while (y > 0) {
		x++;
		z = z + y % 10;
		y = y / 10;
	}
	System.out.println(x + " " + z);
}


	For each call below, indicate what output is produced. 

1) mystery(8);

2) mystery(32);

3) mystery(184);

4) mystery(8239);
