Subsets II

Explore how to generate all unique subsets from an integer array that may contain duplicates. Understand the problem requirements, constraints, and practice implementing solutions to return distinct subsets in any order. This lesson helps develop skills to handle duplicates effectively in subset generation algorithms.

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:

  • 1<=1 <= ...
