349. Intersection of Two Arrays

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

Example 1:

Input: nums1 = [1,2,2,1], nums2 = [2,2]
Output: [2]

Example 2:

Input: nums1 = [4,9,5], nums2 = [9,4,9,8,4]
Output: [9,4]

Note:

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

        :type nums2: List[int]
        :rtype: List[int]

        list = []
        for i in nums1:
            if i in nums2:
                if i not in list:
                    list.append(i)
        return list
