Intersection of Two Arrays

Given two arrays, write a function to compute their intersection.
Example:

Given nums1 =

[1, 2, 2, 1]

, nums2 =

[2, 2]

, return

[2]

.

Note:

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

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

class Solution(object):
def intersection(self, nums1, nums2):
"""
:type nums1: List[int]
:type nums2: List[int]
:rtype: List[int]
"""
res = [str for str in nums1 if str in nums2]
return list(set(res))
