Method

longsum_configurations(int[] elements, int sum)
given a set of integers, returns the number of ways to make them add up to sum, order dependent analogously, 'how many ways can i make change with given coin denominations' 
long[] arr = new long[sum + 1];
arr[0] = 1;
for (int i = 1; i < arr.length; ++i) {
    for (int j : elements)
        if (i - j >= 0)
            arr[i] += arr[i - j];
return arr[sum];
