最大乘积 题目链接:http://acm.hust.edu.cn/vjudge/contest/view.action?cid=84562#problem/B 题意: 输入n个元素组成的序列s,你需要找出一个乘积最大的连续子序列.如果这个最大的乘积不是正数,应输出0. 注意格式. Sample Input32 4 -3 52 5 -1 2 -1 Sample OutputCase #1: The maximum product is 8. Case #2: The maximum product…

问题描述: 问题链接:152 Maximum Product Subarray 在经典的算法解析中, 有关的分治和动态规划的,经典题型之一就是求最大子段和, 这道题就是他的变形:求最大子段积; 这个问题的核心思路与解决最大子段和相同, 但是唯一需要注意的就是负数的情况. 每次在比较当前最大结果的同时,也需要保存当前最小结果,所以每个当前点i处的取值, 就是从当前值nums[i], 和cur_max+nums[i], cur_min+nums[i]三者中取极值: 每次的取值递推路径如上所示, 应该…

Given a sequence of integers S = {S1, S2, ..., Sn}, you shoulddetermine what is the value of the maximum positive product involving consecutive terms of S. Ifyou cannot find a positive sequence, you should consider 0 as the value of the maximum produ…

Given an array of n integers where n > 1, nums, return an array output such that output[i] is equal to the product of all the elements of nums except nums[i]. Solve it without division and in O(n). For example, given [1,2,3,4], return [24,12,8,6]. Fo…

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…

the inner product Givens two vectors \(x,y\in \mathbb{R}^n\), the quantity \(x^\top y\), sometimes called the inner product or dot product of the vectors, is a real number given by: \[x^\top y=\begin{bmatrix}x_1 , x_2 ,\cdots ,x_n \end{bmatrix}\begin…

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. Since two negative numbers may multiply an…
