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…
Description 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. Analysis 题目隶属于分治类型之下,所以最开始就会从“...
Problem Difinition: 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. More practice: If you have fig...
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. More practice: If you have figured out the O(n) solution, try coding another solution using the divide and conquer approach, which is more subtle....
Divide and conquerX + ySublinearGiven an array A of n real numbers, the maximum subarray problem is to find a contiguous subarray which has the largest sum. The k-maximum subarrays problem is to find ksuch subarrays with the...doi:10.1007/978-3-030-34029-2_29Ovidiu Daescu...
Explanation: [4,-1,2,1] has the largest sum = 6. Follow up: If you have figured out the O(n) solution, try coding another solution using the divide and conquer approach, which is more subtle. classSolution(object): defmaxSubArray(self, nums): ...

Given an integer array nums, find the contiguous subarray (containing at least one number) which has the largest sum and return its sum. Example: 解题方法: 需要维护两个变量,global,local。global主要是记录历史最大和...leetcode || 53、Maximum Subarray problem: Find the contiguous subarray withi...
Ans: No, Kadane's algorithm is not a divide-and-conquer algorithm. Q5: Can Kadane's algorithm be used to solve the maximum subarray problem in two-dimensional arrays? Ans: No, Kadane's algorithm is only suitable for one-dimensional arrays. Q6: Can Kadane's algorithm be used to find the...
