This problem involves finding all unique subsets of a given set of integers, which may contain duplicates. The task is to generate these subsets in lexicographical order, ensuring that no subset is repeated. By sorting the input and using a backtracking approach, the algorithm efficiently handles duplicates and outputs all possible combinations, including the empty set.
