While Loop Simulation

	For each call below to the following method, write the value that is returned: 

public static int whileMystery(int a) {
	int b = 1;
	int c = 0;
	while (b <= a) {
		if (b % 2 == 0) {
			c++;
		}
		b = b * 10;
		c++;
	}
	return c + 1;
}

1) whileMystery(2);

2) whileMystery(84)

3) whileMystery(4097)

4) whileMystery(388) 

5) whileMystery(23980)
