<h2><a href="https://leetcode.com/problems/relative-sort-array/">1122. Relative Sort Array</a></h2><h3>Easy</h3><hr><div><p>Given two arrays <code>arr1</code> and <code>arr2</code>, the elements of <code>arr2</code> are distinct, and all elements in <code>arr2</code> are also in <code>arr1</code>.</p>

<p>Sort the elements of <code>arr1</code> such that the relative ordering of items in <code>arr1</code> are the same as in <code>arr2</code>. Elements that do not appear in <code>arr2</code> should be placed at the end of <code>arr1</code> in <strong>ascending</strong> order.</p>

<p>&nbsp;</p>
<p><strong class="example">Example 1:</strong></p>

<pre><strong>Input:</strong> arr1 = [2,3,1,3,2,4,6,7,9,2,19], arr2 = [2,1,4,3,9,6]
<strong>Output:</strong> [2,2,2,1,4,3,3,9,6,7,19]
</pre>

<p><strong class="example">Example 2:</strong></p>

<pre><strong>Input:</strong> arr1 = [28,6,22,8,44,17], arr2 = [22,28,8,6]
<strong>Output:</strong> [22,28,8,6,17,44]
