Add Date 2014-09-23 Maximum Product Subarray Find the contiguous subarray within an array (containing at least one number) which has the largest product. For example, given the array [2,3,-2,4],the contiguous subarray [2,3] has the largest product = …

Find the contiguous subarray within an array (containing at least one number) which has the largest product. For example, given the array [2,3,-2,4],the contiguous subarray [2,3] has the largest product = 6. 这个求最大子数组乘积问题是由最大子数组之和问题演变而来,但是却比求最大子数组之和要复…

Given a list of non-negative numbers and a target integer k, write a function to check if the array has a continuous subarray of size at least 2 that sums up to the multiple of k, that is, sums up to n*k where n is also an integer. Example 1: Input:…

LeetCode Maximum Product Subarray Description Given a sequence of integers S = {S1, S2, . . . , Sn}, you should determine what is the value of the maximum positive product involving consecutive terms of S. If you cannot find a positive sequence, you…

LeetCode 新题又更新了.求:最大子数组乘积. https://oj.leetcode.com/problems/maximum-product-subarray/ 题目分析:求一个数组,连续子数组的最大乘积. 解题思路:最简单的思路就是3重循环.求解productArray[i][j]的值(productArray[i][j]为A[i]到A[j]的乘积),然后记录当中最大值,算法时间复杂度O(n3).必定TLE. 第一次优化,动态规划.求解:productArray[i][j]的时候不用…

1. 子数组的最大和 输入一个整形数组,数组里有正数也有负数.数组中连续的一个或多个整数组成一个子数组,每个子数组都有一个和.求所有子数组的和的最大值.例如数组:arr[]={1, 2, 3, -2, 4, -3 } 最大子数组为 {1, 2, 3, -2, 4} 和为8. 解法1(时间复杂度O(N * N)空间复杂度O(1)) 求出所有的子数组的和,比较选择出最大值.利用双重循环就可以遍历到所有的子数组. public static void maxSum1(int arr[]) { int…

题目 连续子数组求和 给定一个整数数组,请找出一个连续子数组,使得该子数组的和最大.输出答案时,请分别返回第一个数字和最后一个数字的值.(如果两个相同的答案,请返回其中任意一个) 样例 给定 [-3, 1, 3, -3, 4], 返回[1,4]. 解题 法一:直接暴力,时间复杂度O(N2),时间超时 public class Solution { /** * @param A an integer array * @return A list of integers includes the i…

Find the contiguous subarray within an array (containing at least one number) which has the largest product. For example, given the array [2,3,-2,4],the contiguous subarray [2,3] has the largest product = 6. 此题要求是要在一个无需的数组找出一个乘积最大的连续子数组 例如[2,3,-2,4],…
