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] ...

In computer science, the maximum sum subarray problem is the task of finding a contiguous subarray with the largest sum, within a given one-dimensional array A[1...n] of numbers. Formally, the task is to find indices and with, such that the sum is as large as possible. ...

the algorithm of three version below is essentially the same, namely, Kadane’s algorithm, which is of O(n) complexity.https://en.wikipedia.org/wiki/Maximum_subarray_problem the evolution of the implementations is to remove redundancy and do what is really needed, the side effect of doing so...

Choose the maximum by length subarray (continuous subsegment) consisting only of zeros, among all such segments choose the leftmost one; Let this segment be [l;r][l;r] . If r−l+1r−l+1 is odd (not divisible by 22 ) then assign (set) a[l+r2]:=ia[l+r2]:=i (where ii ...
