Description

LeetCode Problem 628.

Given an integer array nums, find three numbers whose product is maximum and return the maximum product.

Example 1:

1
2
Input: nums = [1,2,3]
Output: 6

Example 2:

1
2
Input: nums = [1,2,3,4]
Output: 24

Example 3:

1
2
Input: nums = [-1,-2,-3]
Output: -6

Constraints:

class Solution {
public:
    int maximumProduct(vector<int>& nums) {
        int n = nums.size();
        sort(nums.begin(), nums.end());
        return max(nums[n - 1] * nums[n - 2] * nums[n - 3], nums[0] * nums[1] * nums[n - 1]);
    }
};
