The length of the given array will be in range [3,104] and all elements are in the range [-1000, 1000]. Multiplication of any three numbers in the input won't exceed the range of 32-bit signed integer. 这个题目本质上是一个数学题,需要细心观察才可以得到答案,考虑输入数据分布的几种情形:...
LeetCode 628. Maximum Product of Three Numbers 628. Maximum Product of Three Numbers(三个数的最大乘积) 链接 https://leetcode-cn.com/problems/maximum-product-of-three-numbers/submissions 题目 给定一个整型数组,在数组中找出由三个数组成的最大乘积,并输出这个乘积。 示例1: 输入: [1,2,3] 输出:...
publicintmaximumProduct3(int[] nums){if(nums ==null|| nums.length <3) {return0; }// 定义前三个最大值变量intmax1=Integer.MIN_VALUE;intmax2=Integer.MIN_VALUE;intmax3=Integer.MIN_VALUE;// 定义前两个最小值变量intmin1=Integer.MAX_VALUE;intmin2=Integer.MAX_VALUE;for(intn : nums) {...
Given an integer array, find three numbers whose product is maximum and output the maximum product. Example 1: Input: [1,2,3] Output: 6 1. 2. Example 2: Input: [1,2,3,4] Output: 24 1. 2. 方法一:先排序,考虑数组正负情况, 有点啰嗦但逻辑易懂 int maximumProduct(vector<int>& nums...
Multiplication of any three numbers in the input won't exceed the range of 32-bit signed integer. Solution O(N^3)的暴力破解会超时,这道题的核心思想其实是已知要求3个数的乘积最大,那么要么是数组里面三个最大的正数之积,要么就是最小的两个负数乘上最大的正数。

Write a Python program to compute the maximum product of three numbers in a given array of integers using the heap queue algorithm. Sample Solution: Python Code: defmaximumProduct(nums):importheapq a,b=heapq.nlargest(3,nums),heapq.nsmallest(2,nums)returnmax(a[0]*a[1]*a[2],a[0]*b[...
也可以用扫描: publicclassSolution{publicintmaximumProduct(int[]nums){intmin1=Integer.MAX_VALUE,min2=Integer.MAX_VALUE;intmax1=Integer.MIN_VALUE,max2=Integer.MIN_VALUE,max3=Integer.MIN_VALUE;for(intn:nums){if(n<=min1){min2=min1;min1=n;}elseif(n<=min2){// n lies between min1 an...
628. Maximum Product of Three Numbers Problem: 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 maximum product of these three prime numbers is ( ). 三个质数的和是100,这三个质数的积最大是 .相关知识点: 试题来源: 解析 4514 首先可以肯定必有一个偶数为质数,2然后再排列出来,最大的积只能是与100−22=49相近的质数往下如果为47,则为51⋯. 不符合43,则为55,不符合; 41,则为57,...
