the contiguous subarray[4,−1,2,1]has the largest sum =6. 分析:这道题和152题有点类似。是求连续的子数组的和的最大值。是一道动态规划的题目。 代码如下: publicclassSolution {publicintMaxSubArray(int[] nums) {intmax=int.MinValue,sum=int.MinValue;for(inti=0;i<nums.Length;i++) {if(...
If you have figured out the O(n) solution, try coding another solution using the divide and conquer approach, which is more subtle. 我的解法:两层循环 第一层循环通过i控制进度,第二层循环计算从i 开始的子数组的和的最大值 C#版解法: publicclassSolution {publicintMaxSubArray(int[] nums) {if...
A subarray is a contiguous part of an array. 英文版地址 leetcode.com/problems/m 中文版描述 给你一个整数数组 nums ,请你找出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。子数组 是数组中的一个连续部分。示例1:输入:nums = [-2,1,-3,4,-1,2,1,-5,4]输出:6解释:...
