<p>You are given a <strong>0-indexed</strong> integer array <code>nums</code> of <strong>even</strong> length and there is also an empty array <code>arr</code>. Alice and Bob decided to play a game where in every round Alice and Bob will do one move. The rules of the game are as follows:</p>
<ul>
<li>Every round, first Alice will remove the <strong>minimum</strong> element from <code>nums</code>, and then Bob does the same.</li>
<li>Now, first Bob will append the removed element in the array <code>arr</code>, and then Alice does the same.</li>
<li>The game continues until <code>nums</code> becomes empty.</li>
<strong>Explanation:</strong> In round one, first Alice removes 2 and then Bob removes 3. Then in arr firstly Bob appends 3 and then Alice appends 2. So arr = [3,2].
At the begining of round two, nums = [5,4]. Now, first Alice removes 4 and then Bob removes 5. Then both append in arr which becomes [3,2,5,4].

<pre>
<strong>Input:</strong> nums = [2,5]
<strong>Output:</strong> [5,2]
<strong>Explanation:</strong> In round one, first Alice removes 2 and then Bob removes 5. Then in arr firstly Bob appends and then Alice appends. So arr = [5,2].
