349 - Intersection of Two Arrays\.
Easy
Given two integer arrays `nums1` and `nums2`, return _an array of their intersection_. Each element in the result must be **unique** and you may return the result in **any order**.
**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]
**Explanation:** [4,9] is also accepted.
**Constraints:**
* `1 <= nums1.length, nums2.length <= 1000`
* `0 <= nums1[i], nums2[i] <= 1000`
