Constant time procedure using Java:

public static void main(String[] args) {
    Scanner input = new Scanner(System.in);
    Queue <Integer> myQueue = new LinkedList<Integer>();

    for (int i = 0; i < 3; i++) {
        myQueue.add(input.nextInt());
    }

    int dif1 = myQueue.remove() - input.nextInt();
    int dif2 = myQueue.remove() - input.nextInt();
    int dif3 = myQueue.remove() - input.nextInt();

    if ((dif1 <= 0 && dif2 <= 0 && dif3 <= 0) || (dif1 > 0 && (dif2 < 0 || dif3 < 0)))
        System.out.println(0);
    else if (dif1 > 0 && dif2 == 0 && dif3 == 0) 
        System.out.println(15*dif1);
    else if (dif2 > 0 && dif3 == 0) 
        System.out.println(500*dif2);
    else 
        System.out.println(10000);

}
