<p>You are given the <code>head</code> of a linked list containing unique integer values and an integer array <code>nums</code> that is a subset of the linked list values.</p>
|
|
|
|
<p>Return <em>the number of connected components in </em><code>nums</code><em> where two values are connected if they appear <strong>consecutively</strong> in the linked list</em>.</p>
|
|
|
|
<p> </p>
|
|
<p><strong>Example 1:</strong></p>
|
|
<img alt="" src="https://assets.leetcode.com/uploads/2021/07/22/lc-linkedlistcom1.jpg" style="width: 424px; height: 65px;" />
|
|
<pre>
|
|
<strong>Input:</strong> head = [0,1,2,3], nums = [0,1,3]
|
|
<strong>Output:</strong> 2
|
|
<strong>Explanation:</strong> 0 and 1 are connected, so [0, 1] and [3] are the two connected components.

<strong>Input:</strong> head = [0,1,2,3,4], nums = [0,3,1,4]
|
|
<strong>Output:</strong> 2
|
|
<strong>Explanation:</strong> 0 and 1 are connected, 3 and 4 are connected, so [0, 1] and [3, 4] are the two connected components.
