dp[i] represents the maximum sum of subarray which ends in nums[i], and dp[i] = Math.max(nums[i], dp[i - 1] + nums[i]). and since we have to include nums[i] due to it’s on the defination of dp[i], and when dp[i

The maximum sum subarray problem is to find a contiguous subarray with the largest sum. The history of algorithms to address this problem is recounted, culminating in what is known as Kadane's algorithm. However, that algorithm is not the algorithm Kadane intended. Nonetheless, the algorithm ...
Maximum Size Subarray Sum Equals K Given an arraynumsand a target valuek, find the maximum length of a subarray that sums tok. If there isn't one, return 0 instead. Example 1: Givennums=[1, -1, 5, -2, 3],k=3, return4. (because the subarray[1, -1, 5, -2]sums to 3 and...
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] ...
The second train of thought is, without changing the array, can we use additional space somehow? Like maybe a hash map to speed up the search? Similar Questions 3Sum Medium 4Sum Medium Two Sum II - Input Array Is Sorted Medium Two Sum III - Data structure design Easy Subarray Sum Equals...
Your task is to reverse such a subarray that the sum of elements on even positions of the resulting array is maximized (i. e. the sum of elements a0,a2,…,a2k for integer k=⌊n−12⌋ should be maximum possible). You have to answer t independent test cases. Input The first ...
