Subsets II
Detailed guide and Python implementation for the 'Subsets II' problem.
Problem Statement
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.
Implement a function subsetsWithDup(nums: list) -> list.
- •1 <= nums.length <= 10
- •-10 <= nums[i] <= 10
Examples
[1,2,2]
[[],[1],[1,2],[1,2,2],[2],[2,2]]
Unlike the basic subsets problem, [1,2,2] has duplicate 2's. We skip duplicate subsets like having two copies of [2].
[0]
[[],[0]]
Same as basic subsets for a single element.

Edge Cases to Watch
- Empty input structures
- Single element inputs
- Large numerical bounds
