题目: 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 分析: 给定一个数组,返回其中三个元素乘积的最大值. 注意的是,这道题是可以有负数出现,且是求三个数的乘积,所以我们需要考虑负数的情况. 最先…

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…

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…
