<p>Write a function to delete a node (except the tail) in a singly linked list, given only access to that node.</p>

<p>Given linked list --&nbsp;head =&nbsp;[4,5,1,9], which looks like following:</p>

<p><img alt="" src="https://assets.leetcode.com/uploads/2018/12/28/237_example.png" style="margin-top: 5px; margin-bottom: 5px; width: 300px; height: 49px;" /></p>

<p>&nbsp;</p>

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

<pre>
<strong>Input:</strong> head = [4,5,1,9], node = 5
<strong>Output:</strong> [4,1,9]
<strong>Explanation: </strong>You are given the second node with value 5, the linked list should become 4 -&gt; 1 -&gt; 9 after calling your function.
</pre>

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

<pre>
<strong>Input:</strong> head = [4,5,1,9], node = 1
<strong>Output:</strong> [4,5,9]
<strong>Explanation: </strong>You are given the third node with value 1, the linked list should become 4 -&gt; 5 -&gt; 9 after calling your function.
</pre>

<p>&nbsp;</p>

<p><strong>Note:</strong></p>

<ul>
	<li>The linked list will have at least two elements.</li>
	<li>All of the nodes&#39; values will be unique.</li>
	<li>The given node&nbsp;will not be the tail and it will always be a valid node of the linked list.</li>
	<li>Do not return anything from your function.</li>
</ul>
