Given an integer array nums, find the contiguous subarray (containing at least one number) which has the largest sum and return its sum.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(...
[Leetcode][python]Maximum Subarray/最大子序和 题目大意 由N 个整数元素组成的一维数组 (A[0], A[1],…,A[n-1], A[n]),这个数组有很多连续子数组,那么其中数组之和的最大值是什么呢? 子数组必须是连续的。 不需要返回子数组的具体位置。
Can you solve this real interview question? Maximum Subarray - Given an integer array nums, find the subarray with the largest sum, and return its sum. Example 1: Input: nums = [-2,1,-3,4,-1,2,1,-5,4] Output: 6 Explanation: The subarray [4,-1,2,1]
Leetcode :MaxSubArray 题目 给定一个数列,数列中的数字有正有负,求这个数列中,最大的子数列的和。 Example Input: [-2,1,-3,4,-1,2,1,-5,4], Output: 6 Explanation: [4,-1,2,1] has the largest sum = 6. 思路 这个题其实解法挺多 ...
1和two sum类似,建立一个hashtable,hashtable中累积和是key,index是value 2 如果当前的累积和acc减k存在在hashtable中,则求得长度,由于最后是求最长的subarray,所以其中会有个比较的过程 3 这题和560. Subarray Sum Equals K的区别在于,这题要求最大size,所以hashmap中存的是累积和和index了,560存的是累积和...
