46\. Permutations

Medium

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**.
