Question

Find the sum of all multiples of int m that are less than or equal to int n. Assume that m and n are positive. For example, sumMultiples(3, 10) returns 18 because the multiples of 3 that are less than or equal to 10 are 3, 6, and 9, and 3 + 6 + 9 = 18. sumMultiples(3, 10) → 18 sumMultiples(10, 20) → 30 sumMultiples(10, 9) → 0

Answer 1

int sumMultiples(int m, int n) {
    int sum = 0;
    for (int i = 0; i <= n; i++) {
        if (i % m == 0) {
            sum += i;
        }
    }
    return sum;
}
