一.题目说明 题目是53. Maximum Subarray,求最长连续子序列最大和.难度是Easy! 二.我的解答 Easy的题目,居然没做出来. 后来看了用dp方法,其中dp[i]表示以第i个元素结尾的最大和. dp[i] = nums[i] > nums[i]+dp[i-1] ? nums[i] : nums[i]+dp[i-1]; 然后求出最大的dp即可.知道思路,实现非常简单,问题是没有往动态规划上面去想. #include<iostream> #include<vect…

Maximum Subarray 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. 解法一: 如果当前子串和小于…

题目地址: https://leetcode.com/problems/maximum-subarray/description/ 题目描述: 经典的求最大连续子数组之和. 解法: 遍历这个vector,每次循环累加当前数值,同时更新最大值,若当前的累加和是负数,需要更新为0,因为在进行下一次累加求和的时候, 无论下一个数是正还是负,加上上一次的为负的和,都将变得更小,因而下一次求和时直接从当前值开始计算. 代码: class Solution { public: int maxSubArray…
