Problem - D - Codeforces Example input 5 4 1 2 -1 2 3 1 1 -2 5 2 0 -2 2 -1 3 -2 -1 -1 3 -1 -2 -2 output 0 2 3 0 2 0 0 1 1 0 最近赛中敲不出代码, 赛后倒是镇静了, 我也醉了 简述下思路及变量意义: 这里采取从前到尾遍历,由于数据范围不能完全连乘2e5个的2, 所以我们采取计数方法, num表示绝对值为2的个数, sign表示当前是正负数, min是从上一个0到现在连乘绝对值…

Given an integer array, find three numbers whose product is maximum and output the maximum product. Example 1: Input: [1,2,3] Output: 6 Example 2: Input: [1,2,3,4] Output: 24 Note: The length of the given array will be in range [3,104] and all elemen…

Problem D - Maximum Product Time Limit: 1 second Given a sequence of integers S = {S1, S2, ..., Sn}, you should determine what is the value of the maximum positive product involving consecutive terms ofS. If you cannot find a positive sequence, you s…

problem 628. Maximum Product of Three Numbers 题意:三个数乘积的最大值: solution1: 如果全是负数,三个负数相乘还是负数,为了让负数最大,那么其绝对值就该最小,而负数排序后绝对值小的都在末尾,所以是末尾三个数字相乘,这个跟全是正数的情况一样.那么重点在于前半段是负数,后半段是正数,那么最好的情况肯定是两个最小的负数相乘得到一个正数,然后跟一个最大的正数相乘,这样得到的肯定是最大的数,所以我们让前两个数相乘,再和数组的最后一个数字相乘,就可以…

最大乘积 Maximum Product 题目链接:http://acm.hust.edu.cn/vjudge/contest/view.action?cid=84562#problem/B 解题思路: 题目意思是输入n个元素组成的序列S,找出一个乘积最大的连续子序列.若这个数不是正数,则输出0(表示无解).分析 ,连续子序列有两个要素:起点和终点,因此只需要枚举起点和终点即可.分析最大可能的乘积不会超过10的18次方,所以用 long long 来存储即可. 程序代码: #include <c…

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…
