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`
