2095 - Delete the Middle Node of a Linked List\. Medium You are given the `head` of a linked list. **Delete** the **middle node** , and return _the_ `head` _of the modified linked list_. The **middle node** of a linked list of size `n` is the ⌊n / 2⌋th node from the **start** using **0-based indexing** , where `⌊x⌋` denotes the largest integer less than or equal to `x`. * For `n` = `1`, `2`, `3`, `4`, and `5`, the middle nodes are `0`, `1`, `1`, `2`, and `2`, respectively. **Example 1:**  **Input:** head = [1,3,4,7,1,2,6] **Output:** [1,3,4,1,2,6] **Explanation:** The above figure represents the given linked list. The indices of the nodes are written below. Since n = 7, node 3 with value 7 is the middle node, which is marked in red. We return the new list after removing this node. **Example 2:**  **Input:** head = [1,2,3,4] **Output:** [1,2,4] **Explanation:** The above figure represents the given linked list. For n = 4, node 2 with value 3 is the middle node, which is marked in red. **Example 3:**  **Input:** head = [2,1] **Output:** [2] **Explanation:** The above figure represents the given linked list. For n = 2, node 1 with value 1 is the middle node, which is marked in red. Node 0 with value 2 is the only node remaining after removing node 1. **Constraints:** * The number of nodes in the list is in the range [1, 105]. * 1 <= Node.val <= 105
