4. The maximum sum subarray problem can be stated as follows. Given an array of n integers, A[0..n - 1], find the maximum sum that can be obtained by adding some number of consecutive elements in the array. If all array elements are negative, the maximum sum is 0 (an empty sum). For example, consider the array with elements: 1, 2, 3, -2, 5, 4, 2,-10, 2, 6 Then the maximum sum that can be formed is 9 by summing the first 5 elements. Give a "brute force" algorithm to solve the maximum subarray sum problem in (n²) operations. Show your analysis.

Question
Hi I was wondering if I could get help with this question.
I know that the first five will make the largest sum of 9 but I don't where to go from there
Thanks
