:END:

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:*


#+begin_src
Input: nums = [1,2,2]
Output: [[],[1],[1,2],[1,2,2],[2],[2,2]]
#+end_src
*Example 2:*


#+begin_src
Input: nums = [0]
Output: [[],[0]]
#+end_src


*Constraints:*

 - ~1 <= nums.length <= 10~

 - ~-10 <= nums[i] <= 10~
