It is but that recursive can be converted to one for loop since every maxSum(i) will end up calling maxSum(0). Thus if we go from 0 to i and calculate and store the results (or at least the last result) the time complexity of the algorithm will be linear O(n). Brute force on the other hand, we have to find all the subarray and calculate the sum for each and then find the max of the results.

Does this imply recursion? How is this better than the brute force one? Thanks for your reply.
