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:

1. The length of the given array will be in range [3,104] and all elements are in the range [-1000, 1000].
2. Multiplication of any three numbers in the input won't exceed the range of 32-bit signed integer.

    def maximumProduct(self, nums):

        :type nums: List[int]

        :rtype: int

        """

        n=sorted(nums)

        return max(n[-1]*n[-2]*n[-3],n[0]*n[1]*n[-1])
