Middle of the Linked List
Given the head of a singly linked list, return the middle node of the linked list. If there are two middle nodes, return the second middle node. Example 1: Input: head = [1,2,3,4,5] Output: [3,4,5] Explanation: The middle node of the list is node 3. Example 2: Input: head = [1,2,3,4,5,6] Output: [4,5,6] Explanation: Since the list has two middle nodes with values 3 and 4, we return the second one. Constraints: The number of nodes in the list is in the range [1, 100]. 1 <= Node.val <= 100
Test case 1
Input
head = [1,2,3,4,5]
Output
[3,4,5]
Test case 2
Input
head = [1,2,3,4,5,6]
Output
[4,5,6]
