While Loop Simulation

	Consider the following method: 

public static void mystery(int n) {
	int x = 1;
	int y = 1;
	while (n > y) {
		x++;
		y = 10 * y + x;
	}
	System.out.println(x + " " + y);
}


	For each call below, indicate what output is produced. 

1) mystery(0);

2) mystery(7);

3) mystery(32);

4) mystery(256);
