    2326 - Spiral Matrix IV\. Medium You are given two integers `m` and `n`, which represent the dimensions of a matrix. You are also given the `head` of a linked list of integers. Generate an `m x n` matrix that contains the integers in the linked list presented in **spiral** order **(clockwise)** , starting from the **top-left** of the matrix. If there are remaining empty spaces, fill them with `-1`. Return _the generated matrix_. **Example 1:** ![](https://assets.leetcode.com/uploads/2022/05/09/ex1new.jpg) **Input:** m = 3, n = 5, head = [3,0,2,6,8,1,7,9,4,2,5,5,0] **Output:** [[3,0,2,6,8],[5,0,-1,-1,1],[5,2,4,9,7]] **Explanation:** The diagram above shows how the values are printed in the matrix. Note that the remaining spaces in the matrix are filled with -1. **Example 2:** ![](https://assets.leetcode.com/uploads/2022/05/11/ex2.jpg) **Input:** m = 1, n = 4, head = [0,1,2] **Output:** [[0,1,2,-1]] **Explanation:** The diagram above shows how the values are printed from left to right in the matrix. The last space in the matrix is set to -1. **Constraints:** * 1 <= m, n <= 105 * 1 <= m * n <= 105 * The number of nodes in the list is in the range `[1, m * n]`. * `0 <= Node.val <= 1000`
