90\. Subsets II
Medium
Given an integer array `nums` that may contain duplicates, return _all possible subsets (the power set)_.
The solution set **must not** contain duplicate subsets. Return the solution in **any order**.
**Example 1:**
**Input:** nums = [1,2,2]
**Output:** [[],[1],[1,2],[1,2,2],[2],[2,2]]
**Example 2:**
**Input:** nums = [0]
**Output:** [[],[0]]
**Constraints:**
* `1 <= nums.length <= 10`
* `-10 <= nums[i] <= 10`
