So I change the format of the sub problem into something like:maxSubArray(int A[], int i), which means the maxSubArray for A[0:i ] which must has A[i] as the end element. Note that now the sub problem's format is less flexible and less powerful than the previous one because the...

I am getting WA on test 28 ofthisproblem. Would really appreciate all the help. My Approach Basically, I am partitioning each segment[l…r][l…r]into three partitions,p1,p2,p3p1,p2,p3where p2p2= maximum subarray sum in[l…r][l…r] ...
When an overlapping property needs to be observed, previous algorithms for the maximum sum are not directly applicable. We designed an O(K * n) algorithm for the K maximum subsequences problem. This was then modified to solve the K maximum subarrays problem in O(K * n3) time. Finally, ...
(5kyu) The maximum sum subarray problem consists in finding the maximum sum of a contiguous subsequence in an array or list of integers: maxSequence([-2 , 1, -3, 4, -1 , 2, 1, -5, 4]) # should be 6: [4, -1, 2, 1] ...
