<p>Given a fixed length&nbsp;array <code>arr</code> of integers, duplicate each occurrence of zero, shifting the remaining elements to the right.</p>

<p>Note that elements beyond the length of the original array are not written.</p>

<p>Do the above modifications to the input array <strong>in place</strong>, do not return anything from your function.</p>

<p>&nbsp;</p>

<p><strong>Example 1:</strong></p>

<pre>
<strong>Input: </strong><span id="example-input-1-1">[1,0,2,3,0,4,5,0]</span>
<strong>Output: </strong>null
<strong>Explanation: </strong>After calling your function, the <strong>input</strong> array is modified to: <span id="example-output-1">[1,0,0,2,3,0,0,4]</span>

<p><strong>Example 2:</strong></p>

<pre>
