Note:

Each element in the result must be unique.The result can be in any order.

Explain

python写真的太简洁

Code

class Solution(object): def intersection(self, nums1, nums2): """ :type nums1: List[int] :type nums2: List[int] :rtype: List[int] """ import collections return list(set(collections.Counter(nums1) & collections.Counter(nums2)))
