any two numbers that are in the same bucket cannot be the answer. Thus, we only need to store the largest number and the smallest number in each bucket. Then, we can scan the buckets sequentially and get a sorted list. The maximum difference between two consecutive elements is the answer...
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 elements are in the range [-...
