817 - Linked List Components.

Medium

You are given the head of a linked list containing unique integer values and an integer array nums that is a subset of the linked list values.

Return the number of connected components in nums where two values are connected if they appear consecutively in the linked list.

Example 1:

Input: head = [0,1,2,3], nums = [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], nums = [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.

Constraints:

• The number of nodes in the linked list is n.
• 1 <= n <= 104
• 0 <= Node.val < n
• All the values Node.val are unique.
• 1 <= nums.length <= n
• 0 <= nums[i] < n
• All the values of nums are unique.
