Lintcode41 Maximum Subarray solution 题解 【题目描述】 Given an array of integers, find a contiguous subarray which has the largest sum. Notice:The subarray should contain at least one number. 给定一个整数数组,找到一个具有最大和的子数组,返回其最大和。
Given an array, we need to find two subarrays with a specific length K such that sum of these subarrays is maximum among all possible choices of subarrays. arr size <10^5 n<10^3 Examples: Input : arr[] = [2, 5, 1, 2, 7, 3, 0] ...
The suffix of the left subtree with greatest sum * length is the empty suffix with sum * length = 0. But the optimal solution is to take the entire string since the sum in the right subtree outweighs the negative sum in the left subtree. (And you can't fix this by adding it as ...
