网址:https://leetcode.com/problems/maximum-subarray/submissions/ 很简单的动态规划 我们可以把 dp[i] 表示为index为 i 的位置上的Maximum 容易得出,dp[i] = max( nums[i] , dp[i-1] + nums[i] ) 最后再把dp数组转化为两个变量之间的关系,可以减少内存开销! class Solution { public: int maxSubArray(vector<int>& num…

题目: Given an integer array nums, find the contiguous subarray (containing at least one number) which has the largest sum and return its sum. Example: Input: [-2,1,-3,4,-1,2,1,-5,4], Output: 6 Explanation: [4,-1,2,1] has the largest sum = 6. Follow up…

这道题是LeetCode里的第53道题. 题目描述: 给定一个整数数组 nums ,找到一个具有最大和的连续子数组(子数组最少包含一个元素),返回其最大和. 示例: 输入: [-2,1,-3,4,-1,2,1,-5,4], 输出: 6 解释: 连续子数组 [4,-1,2,1] 的和最大,为 6. 进阶: 如果你已经实现复杂度为 O(n) 的解法,尝试使用更为精妙的分治法求解. 简单的动态规划题,如果之前接触过动态规划的话很容易得出答案,没有的话估计得想一阵子. 不多废话,我先介绍一下什么是动态规…

Given an array of integers, find a contiguous subarray which has the largest sum. Notice The subarray should contain at least one number. Have you met this question in a real interview? Yes Example Given the array [−2,2,−3,4,−1,2,1,−5,3], the contigu…

题目: Find the contiguous subarray within an array (containing at least one number) which has the largest sum. For example, given the array [-2,1,-3,4,-1,2,1,-5,4],the contiguous subarray [4,-1,2,1] has the largest sum = 6. 题解: 遍历所有组合,更新最大和. Solution 1…

Find the contiguous subarray within an array (containing at least one number) which has the largest sum. For example, given the array [−2,1,−3,4,−1,2,1,−5,4],the contiguous subarray [4,−1,2,1] has the largest sum = 6. click to show more practice. Mor…
