static int recursive_sum(Vector pymts)
{
// eturn condition
if (pymts.size() == 0) return 0;

// recursive steps, vector has at least size of 1, of payment type (assume all objects are class Payment)
return pymts.remove(0).sum + recursive_sum(pymts);
}

Above is destructive recursive and a lot of school doesn't like it cause at the end. The original vector will become empty.

Just make a shadow copy before recurse
