Problem: Permutations II

med
30 min
Explore how to find all unique permutations of an integer list containing duplicates. Learn methods to handle duplicates effectively and code an optimal solution in a concise, hands-on environment.

Statement

For a given integer list, nums, which might contain duplicates, return all possible unique permutations derived from nums.

Note: The order in which the permutations appear doesn’t matter.

Constraints:

  • 1≤1 \leq nums.length ≤8\leq 8

  • −10≤-10 \leq nums[i] ≤10\leq 10
