LeetCode - The World's Leading Online Programming Learning Platformleetcode.com/problems/maximum-gcd-sum-of-a-subarray/description/ 简单介绍一下题目大意,更详细的描述可以见链接中的原题描述及样例数据: 给定一个长度为n的正整数数组nums。对于nums
代码(Python3) class Solution: def maximumSubarraySum(self, nums: List[int], k: int) -> int: # ans 维护所有长度为 k 且数字各不相同的子数组中,子数组和的最大值 ans: int = 0 # sum 维护当前滑动窗口 [l, r] 内的数字和 sum: int = 0 # num_to_cnt 表示滑动窗口 [l, r] 内每个数...
题目地址: https://leetcode.com/problems/maximum-sum-of-3-non-overlapping-subarrays/description/ 题目描述: In a given array nums of positive integers, find three non-overlapping subarrays with maximum sum. Each subarray will be of size k, and we want to maximize the sum of all 3*k entri...
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...
LeetCode 0053. Maximum Subarray最大子序和【Easy】【Python】【动态规划】 Problem LeetCode Given an integer arraynums, find the contiguous subarray (containing at least one number) which has the largest sum and return its sum. Example:
Leetcode 1031 Maximum Sum of Two Non-Overlapping Subarrays (两个不重叠子数组的最大和) (滑动窗口) Leetcode 1031题目描述Given an array A of non-negative integers, return the maximum sum of elements in two non-overlapping (contiguous) subarrays, which have lengths L and M. (For clarification...
[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。
问题描述: Given an array consisting of n integers, find the contiguous subarray of given lengthk that has the maximum average value. And you need to output the maximum average value. 示例: Input: [1,12,-5,-... 用Python刷LeetCode【53. 最大子序和(Maximum Subarray)】 ...
Leetcode 53. Maximum Subarray 2. Solution **解析:**Version 1,简单粗暴,前i个元素总和大于0,则这些元素对总和是有贡献的,要保留,否则,则丢弃前i个元素。重新开始执行上述操作,每次加完记得更新最大值。Version 2,采用动态规划求解,首先定义状态,dp[i]是以nums[i]为结尾的连续子数组的最大和,状态转移方程...
https://leetcode-cn.com/problems/maximum-subarray/ 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 DP,设定dp[i]是以元素...
