Delete the Middle Node of a Linked List Problem Statement Given the head of a linked list of integers, delete the middle node of the linked list and return the modified head. If the linked list has an even number of nodes, delete the second middle node. Input Specification The input will be a linked list LL. Output Specification Return the head of the modified linked list after deleting the appropriate middle node. Constraints No explicit constraints are provided in the original content for the size of the linked list or the range of values within the nodes. Sample Test Cases Example 1: Input Format: LL: 1 2 3 4 5 Output: 1 2 4 5 Explanation: Node with value 3 is the middle node and is deleted. Example 2: Input Format: LL: 1 2 3 4 Output: 1 2 4 Explanation: The linked list has an even number of nodes, so the second middle node (node with value 3) is deleted.
