# 移除链表元素

给你一个链表的头节点 <code>head</code> 和一个整数 <code>val</code> ，请你删除链表中所有满足 <code>Node.val == val</code> 的节点，并返回 <strong>新的头节点</strong> 。

<strong>输入：</strong>head = [1,2,6,3,4,5,6], val = 6
<strong>输出：</strong>[1,2,3,4,5]
</pre>

<p><strong>示例 2：</strong></p>

<pre>
<strong>输入：</strong>head = [], val = 1
<strong>输出：</strong>[]
</pre>

<p><strong>示例 3：</strong></p>

<pre>
<strong>输入：</strong>head = [7,7,7,7], val = 7
<strong>输出：</strong>[]
</pre>

<p> </p>

<p><strong>提示：</strong></p>

<ul>
	<li>列表中的节点数目在范围 <code>[0, 10<sup>4</sup>]</code> 内</li>
	<li><code>1 <= Node.val <= 50</code></li>
	<li><code>0 <= val <= 50</code></li>
</ul>


## template

```java
public class ListNode {
	int val;
	ListNode next;

	ListNode(int x) {
		val = x;
	}
}

class Solution {
	public ListNode removeElements(ListNode head, int val) {
		ListNode top = new ListNode(0);
		top.next = head;
		ListNode pre = top;
		ListNode temp = head;
		while (temp != null) {
			if (temp.val == val)
				pre.next = temp.next;
			else
				pre = temp;
			temp = temp.next;
		}
		return top.next;
	}
}
