Spiral Matrix IV
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.
