While Loop Simulation

	For each call below to the following method, write the output that is printed, as it would appear on the console: 

public static void mystery(int x, int y, int z) {
	while (x >= y && x > z) {
		x = x - z;
		y--;
		z++;
	}
	System.out.println(x + " " + y + " " + z);
}

1) mystery(31, 4, 15);

2) mystery(8, 4, 2); 

3) mystery(0, 0, 7); 

4) mystery(9, 1, 1);
