 ## Description
+Given two integer arrays `nums1` and `nums2`, return an array of their intersection. Each element in the result must appear as many times as it shows in both arrays and you may return the result in **any order**.
 
 **Example 1:**
 
 ```
-Input: a = "11", b = "1"
-Output: "100"
+Input: nums1 = [1,2,2,1], nums2 = [2,2]
+Output: [2,2]
 ```
