pseudocode is fine BUT PLEASE COMMENT EVERY STEP

4.1-5 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 in- dex 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 Ai..j + 1], for some 1
