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
代码(Python3) class Solution: def checkSubarraySum(self, nums: List[int], k: int) -> bool: # remain_to_first_index 维护每一个前缀和 % k 第一次出现的下标 remain_to_first_index: Dict[int, int] = {} # 初始前缀和 0 % k 的下标为 -1 ,方便处理整个前缀和满足题意的情况 remain_to...
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, the L-length subarray could occur before or after the M-length subarray.) Formally, return the largest V for which ...
In a given arraynumsof positive integers, find three non-overlapping subarrays with maximum sum. Each subarray will be of sizek, and we want to maximize the sum of all3*kentries. Return the result as a list of indices representing the starting position of each interval (0-indexed). If ...
Q1: Is Kadane's algorithm suitable for finding the maximum sum of a non-contiguous subarray? Ans: No, Kadane's algorithm is only suitable for finding the maximum sum of a contiguous subarray. Q2: Can Kadane's algorithm handle arrays with negative numbers? Ans: Yes, Kadane's algorithm can...
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...
定义两个指针left和right,分别记录子数组的左右的边界位置,然后我们让right向右移,直到子数组和大于等于给定值或者right达到数组末尾,此时我们更新最短距离,并且将left像右移一位,然后再sum中减去移去的值,然后重复上面的步骤,直到right到达末尾,且left到达临界位置,即要么到达边界,要么再往右移动,和就会小于给定值。
题目地址: https://leetcode.com/problems/minimum-size-subarray-sum/description/题目描述:Given an array of n positive integers and a positive integer s, find the minimal length of a contiguous subarray of which the sum ≥ s. If there isn’t one, return 0 instead....
In this tutorial, we will be discussing a program to find maximum subarray size, such that all subarrays of that size have sum less than k. For this we will be provided with an array of size N and an integer k. Our task is to find the length of subarray such that all the...
传送门:718. Maximum Length of Repeated Subarray Problem: Given two integer arrays A and B, return the maximum length of an subarray that appears in both arrays. Example 1: Input: A: [ 1,2,3,2,1] B: [3,2,1,4,7] Output: 3 Explanation: The repeated subarray with maximum length is...
