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…
