While Loop Simulation

	Consider the following method: 

public static void mystery(int n) {
	int x = 1;
	int y = 1;
	while (n > 2) {
		x = x + y;
		y = x - y;
		n--;
	}
	System.out.println(x);
}


	For each call below, indicate what output is produced. 

1) mystery(1);

2) mystery(3);

3) mystery(5);

4) mystery(7);
