public static int mystery(int a) {
    int b = 0;
    int c = 0;
   
    // Point A
    while (a != 0) {
        // Point B
        c = a % 10;

        if (c % 2 == 0) {
            b++;
        } else {
            b = 0;
            // Point C
        }
       
        a = a / 10;
        // Point D
    }
