class Solution:
    def intersection(self, nums1, nums2):
        result = set()
        for x in nums1:
            if x in nums2:
                result.add(x)
        return list(result)

class Solution:
    def intersection(self, nums1, nums2):
        result = set()
        stat = {}
        for x in nums1:
            stat[x] = x

        for x in nums2:
            if x in stat:
                result.add(x)

        return list(result)

class Solution:
    def intersection(self, nums1, nums2):
        return list(set(nums1) & set(nums2))
