<p>给你一个链表的头节点 <code>head</code> 和一个特定值<em> </em><code>x</code> ,请你对链表进行分隔,使得所有 <strong>小于</strong> <code>x</code> 的节点都出现在 <strong>大于或等于</strong> <code>x</code> 的节点之前。</p>
|
||||
|
||||
<p>你应当 <strong>保留</strong> 两个分区中每个节点的初始相对位置。</p>
|
||||
|
||||
<p> </p>

<p><strong>示例 1:</strong></p>
|
||||
<img alt="" src="https://assets.leetcode.com/uploads/2021/01/04/partition.jpg" style="width: 662px; height: 222px;" />

<pre>
|

<strong>输入:</strong>head = [1,4,3,2,5,2], x = 3

||||
<strong>输出</strong>:[1,2,2,4,3,5]
