Write a Program to Find Maximum Product of Three Numbers

# 628. Maximum Product of Three Numbers

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

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

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

Constraints:
```
3 <= nums.length <= 104
-1000 <= nums[i] <= 1000
```

/**
 * @param {number[]} nums
 * @return {number}
 */
var maximumProduct = function(nums) {
    nums.sort((a, b) => b - a);
    return Math.max(nums[0]*nums[1]*nums[2], nums[nums.length-1]*nums[nums.length-2]*nums[0]);
};
