Write a function named Cumulative that accepts as a parameter a reference to a vector of integers, and modifies it so that each element contains the cumulative sum of the elements up through that index. For example, if the vector passed contains {1, 1, 2, 3, 5}, your function should modify it to store {1, 2, 4, 7, 12).
