Exercise : assertions

Identify whether each assertion is always/never/sometimes true at each point.

	x > y	z == 0	x == y
A	(choose) ALWAYS NEVER SOMETIMES SOMETIMES	(choose) ALWAYS NEVER SOMETIMES ALWAYS	(choose) ALWAYS NEVER SOMETIMES SOMETIMES
B	(choose) ALWAYS NEVER SOMETIMES SOMETIMES	(choose) ALWAYS NEVER SOMETIMES SOMETIMES	(choose) ALWAYS NEVER SOMETIMES NEVER
C	(choose) ALWAYS NEVER SOMETIMES ALWAYS	(choose) ALWAYS NEVER SOMETIMES NEVER	(choose) ALWAYS NEVER SOMETIMES NEVER
D	(choose) ALWAYS NEVER SOMETIMES NEVER	(choose) ALWAYS NEVER SOMETIMES NEVER	(choose) ALWAYS NEVER SOMETIMES NEVER
E	(choose) ALWAYS NEVER SOMETIMES NEVER	(choose) ALWAYS NEVER SOMETIMES SOMETIMES	(choose) ALWAYS NEVER SOMETIMES ALWAYS

public static void mystery(int x, int y) {
    int z = 0;

    // Point A
    while (x != y) {
        // Point B
        z++;

        if (x > y) {
            // Point C
            x = x / 10;
        } else {
            // Point D
            y = y / 10;
        }
    }

    // Point E
    System.out.println(x + " " + y + " " + z);
}
