<p>给你一个长度固定的整数数组&nbsp;<code>arr</code>,请你将该数组中出现的每个零都复写一遍,并将其余的元素向右平移。</p>
<p>注意:请不要在超过该数组长度的位置写入元素。</p>
<p>要求:请对输入的数组&nbsp;<strong>就地&nbsp;</strong>进行上述修改,不要从函数返回任何东西。</p>
<p>&nbsp;</p>
<p><strong>示例 1</strong></p>
<pre><strong>输入:</strong>[1,0,2,3,0,4,5,0]
<strong>输出:</strong>null
<strong>解释:</strong>调用函数后,<strong>输入</strong>的数组将被修改为:[1,0,0,2,3,0,0,4]
</pre>
<p><strong>示例 2</strong></p>
<pre><strong>输入:</strong>[1,2,3]
<strong>输出:</strong>null
<strong>解释:</strong>调用函数后,<strong>输入</strong>的数组将被修改为:[1,2,3]
</pre>
<p>&nbsp;</p>
<p><strong>提示:</strong></p>
<ol>
<li><code>1 &lt;= arr.length &lt;= 10000</code></li>
<li><code>0 &lt;= arr[i] &lt;= 9</code></li>
</ol>
