Given the <code>head</code> of a linked list and an integer <code>val</code>, remove all the nodes of the linked list that has <code>Node.val == val</code>, and return the new head.

&nbsp;
Example 1:
<img alt="" src="https://assets.leetcode.com/uploads/2021/03/06/removelinked-list.jpg" style="width: 500px; height: 142px;" />
<pre>
Input: head = [1,2,6,3,4,5,6], val = 6
Output: [1,2,3,4,5]
</pre>

Example 2:

<pre>
Input: head = [], val = 1
Output: []
</pre>

Example 3:

<pre>
Input: head = [7,7,7,7], val = 7
Output: []
</pre>

&nbsp;
Constraints:

<ul>
	<li>The number of nodes in the list is in the range <code>[0, 104]</code>.</li>
	<li><code>1 &lt;= Node.val &lt;= 50</code></li>
	<li><code>0 &lt;= val &lt;= 50</code></li>
</ul>
