#2) The maximum subarray problem can be solved in linear time. Use the following ideas to develop a nonrecursive, linear-time algorithm for the maximum-subarray problem.
Start at the left end of the array, and progress toward the right, keeping track of the maximum subarray seen so far. Knowing a maximum subarray of A[1 .. j], extend the answer to find a maximum subarray ending at index j+1 by using the following observation: a maximum subarray of A[1 .. j + 1] is either a maximum subarray of A[1 .. j] or a subarray A[i .. j + 1], for some 1 <= i <= j + 1. Determine a maximum subarray of the form A[i .. j + 1] in constant time based on knowing a maximum subarray ending at index j.
Please write commented C++ Code, and show a sample output.
