# 1122. Relative Sort Array

<https://leetcode.com/problems/relative-sort-array>

## Description

Given two arrays `arr1` and `arr2`, the elements of `arr2` are distinct, and all elements in `arr2` are also in `arr1`.

Sort the elements of `arr1` such that the relative ordering of items in `arr1` are the same as in `arr2`. Elements that do not appear in `arr2` should be placed at the end of `arr1` in **ascending** order.

**Example 1:**

```
**Input:** arr1 = [2,3,1,3,2,4,6,7,9,2,19], arr2 = [2,1,4,3,9,6]
**Output:** [2,2,2,1,4,3,3,9,6,7,19]
```

**Example 2:**

```
**Input:** arr1 = [28,6,22,8,44,17], arr2 = [22,28,8,6]
**Output:** [22,28,8,6,17,44]
```

**Constraints:**

* `1 <= arr1.length, arr2.length <= 1000`
* `0 <= arr1[i], arr2[i] <= 1000`
* All the elements of `arr2` are **distinct**.
* Each `arr2[i]` is in `arr1`.
