Solution: Subsets II
Discover how to use backtracking to generate all unique subsets from a sorted integer array containing duplicates. This lesson guides you through avoiding duplicate subsets by skipping repeated elements at each recursion level, helping you master depth-first search for subset problems in C#.

Statement
Given an integer array nums, that can contain duplicate elements, return all possible subsets while ensuring that each subset is unique. The output must include unique subsets, and you may return them in any order.
Constraints:
