Set element zero of the second array equal to element zero of the first. Loop through the original array, starting at element 1. On each iteration, update the current element of the summed array to ...

As soon as the whole array has the sum from each of its elements, the recursive invocations stops. Once all the elements of the array are summed recursively, we show the result. Listing 1.

The problem with this brute-force approach to the prefix sum problem is that it is highly inefficient. Discrete logic must be performed on every element of the array. As arrays become larger, the ...
