If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23.
Find the sum of all the multiples of 3 or 5 below 1000.

int result = 0;
for (int i=0; i<1000; i++) {
	if (i%3==0 || i%5==0) {
		result += i;
	}
}
System.out.println(result);
