# 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**.
