<h2><a href="https://leetcode.com/problems/find-the-winner-of-an-array-game">1657. Find the Winner of an Array Game</a></h2><h3>Medium</h3><hr><p>Given an integer array <code>arr</code> of <strong>distinct</strong> integers and an integer <code>k</code>.</p>

<p>A game will be played between the first two elements of the array (i.e. <code>arr[0]</code> and <code>arr[1]</code>). In each round of the game, we compare <code>arr[0]</code> with <code>arr[1]</code>, the larger integer wins and remains at position <code>0</code>, and the smaller integer moves to the end of the array. The game ends when an integer wins <code>k</code> consecutive rounds.</p>

<p>Return <em>the integer which will win the game</em>.</p>

<p>It is <strong>guaranteed</strong> that there will be a winner of the game.</p>

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

<pre>
<strong>Input:</strong> arr = [2,1,3,5,4,6,7], k = 2
<strong>Output:</strong> 5
<strong>Explanation:</strong> Let&#39;s see the rounds of the game:
Round |       arr       | winner | win_count
  1   | [2,1,3,5,4,6,7] | 2      | 1
  2   | [2,3,5,4,6,7,1] | 3      | 1
  3   | [3,5,4,6,7,1,2] | 5      | 1
  4   | [5,4,6,7,1,2,3] | 5      | 2
So we can see that 4 rounds will be played and 5 is the winner because it wins 2 consecutive games.
</pre>

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

<pre>
<strong>Input:</strong> arr = [3,2,1], k = 10
<strong>Output:</strong> 3
<strong>Explanation:</strong> 3 will win the first 10 rounds consecutively.
