Problem: While Loop Simulation

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

public static void mystery(int x, int y) {
	int z = 1;
	while (x > 0) {
		System.out.print(y + ", ");
		y = y - z;
		z = z + y;
		x--;
	}
	System.out.println(y);
}

1) mystery(2, 3);

2) mystery(3, 5);

3) mystery(4, 7);
