We are given head
, the head node of a linked list containing unique integer values.
We are also given the list G
, a subset of the values in the linked list.
Return the number of connected components in G
, where two values are connected if they appear consecutively in the linked list.
Example 1:
Input: head: 0->1->2->3 G = [0, 1, 3] Output: 2 Explanation: 0 and 1 are connected, so [0, 1] and [3] are the two connected components.
Example 2:
Input: head: 0->1->2->3->4 G = [0, 3, 1, 4] Output: 2 Explanation: 0 and 1 are connected, 3 and 4 are connected, so [0, 1] and [3, 4] are the two connected components.
Note:
<li>If <code>N</code> is the length of the linked list given by <code>head</code>, <code>1 <= N <= 10000</code>.</li>
<li>The value of each node in the linked list will be in the range<code> [0, N - 1]</code>.</li>
<li><code>1 <= G.length <= 10000</code>.</li>
<li><code>G</code> is a subset of all values in the linked list.</li>
