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. 很显然是一个动态规划的问题,找到递归表达式就可以了,考虑到会有负负相乘的问题,所以应…

题目 乘积最大子序列 找出一个序列中乘积最大的连续子序列(至少包含一个数). 样例 比如, 序列 [2,3,-2,4] 中乘积最大的子序列为 [2,3] ,其乘积为6. 解题  法一:直接暴力求解 时间复杂度O(N2) public class Solution { /** * @param nums: an array of integers * @return: an integer */ public int maxProduct(int[] nums) { // write your c…

题目链接:Maximum Product Subarray solutions同步在github 题目很简单,给一个数组,求一个连续的子数组,使得数组元素之积最大.这是求连续最大子序列和的加强版,我们可以先看看求连续最大子序列和的题目maximum-subarray,这题不难,我们举个例子. 假设数组[1, 2, -4, 5, -1, 10],前两个相加后得到3,更新最大值(为3),然后再加上-4后,和变成-1了,这时我们发现如果-1去加上5,不如舍弃前面相加的sum,5单独重新开始继续往后相加…

题目: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 [,,-,], the contiguous subarray [,] has the largest product = . 这道题属于动态规划的题型,之前常见的是M…
