For each of the five points labeled by comments, identify each of the assertions in the table below as either being always true, never true, or sometimes true / sometimes false. You may assume that no int values overflow their valid ranges.

public static int mystery(Scanner console, int x) {
    int y = console.nextInt();
    int count = 0;

    // Point A
    while (y < x) {
        // Point B
        if (y == 0) {
            count++;
            // Point C
        }

        y = console.nextInt();
        // Point D
    }

    // Point E
    return count;
}

Fill in each box of the the table below with ALWAYS, NEVER or SOMETIMES.

y < x y == 0 count > 0
Point A
Point B
