(Formally, for a subarray C[i], C[i+1], ..., C[j], there does not exist i <= k1, k2 <= j with k1 % A.length = k2 % A.length.) Example 1:Input: [1,-2,3,-2] Output: 3 Explanation: Subarray [3] has maximum sum 3 Example 2:Input: [5,-3,5] Output: 10 ...
In a given arraynumsof positive integers, find three non-overlapping subarrays with maximum sum. Each subarray will be of sizek, and we want to maximize the sum of all3*kentries. Return the result as a list of indices representing the starting position of each interval (0-indexed). If ...
The solution I presented isO(nlog)O(n), since I make use of std::set. However, you can use another variablemimsuch that is represents the minimum of that set. We can update it as follows:minv=min(minv,p[r−1])minv=min(minv,pf[r−1])once you are done withrr. Also, you...

MaxSubArraySum是一种经典的算法问题,其目标是在给定的整数数组中找到具有最大总和的连续子数组。解决这个问题的常见方法是使用动态规划。算法的基本思想是维护两个变量:当前子数组的最大和以及全局最大和。在遍历数组时,我们不断更新当前子数组的最大和,如果该和变得小于0,则重新开始计算子数组和,并更新全局最大和...
we're essentially looking for at everyiis the largestjsuch that it's prefix sum is <= pref[i] — k (the largest j so that we can cut off as much of the array as possible). This problem can be solved with a segment tree that handles point updates and stores the max on a range...
