问题简介 本文将介绍计算机算法中的经典问题——最大子数组问题(maximum subarray problem)。所谓的最大子数组问题,指的是:给定一个数组A,寻找A的和最大的非空连续子数组。比如,数组 A = [-2, -3, 4, -1, -2…
leetcode---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. 本题就是求最大字段和...
【刷题笔记】53. Maximum Subarray 题目 Given an integer arraynums, find the contiguous subarray (containing at least one number) which has the largest sum and return its sum. Example: AI检测代码解析 Input: [-2,1,-3,4,-1,2,1,-5,4],...
LeetCode 最大子序和(Maximum Subarray) 题目 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。 解题思路 暴力法:从数组的每个节点开始向...

53. 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. ...
the contiguous subarray [4,-1,2,1] has the largest sum = 6.中文:主要是给定一个数组,求解数组的子数组中,数组元素和最大的那一个子数组,返回的是最大子数组的和。2. 求解解法一最简单也是最容易想到的思路就是三层循环,对(i,j),i<=j的情况进行遍历,这种情况下的算法复杂度为O($n^3$)。代码如...
