Given an integer array nums, find three numbers whose product is maximum and return the maximum product.
Example 1:
Input: nums = [1,2,3] Output: 6
Example 2:
Input: nums = [1,2,3,4] Output: 24
Example 3:
Input: nums = [-1,-2,-3] Output: -6
Constraints:
3 <= nums.length <= 104-1000 <= nums[i] <= 1000
