    Given an array nums of distinct integers, return all the possible permutations. You can return the answer in any order.

    Example 1:

    Input: nums = [1,2,3]

    Output: [[1,2,3],[1,3,2],[2,1,3],[2,3,1],[3,1,2],[3,2,1]]

    Example 2:

    Input: nums = [0,1]

    Output: [[0,1],[1,0]]

    Example 3:

    Input: nums = [1]

    Output: 1

    Constraints:

    • 1 <= nums.length <= 6
    • -10 <= nums[i] <= 10
    • All the integers of nums are unique.
