Subsets II

Explore how to generate all unique subsets from an integer array that may contain duplicates. This lesson helps you understand problem constraints and implement solutions that avoid duplicate subsets using Python, enhancing your grasp of subsets in coding interviews.

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 <= ...
