Understanding the Spiral Matrix I V Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
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.

Examples
m = 3, n = 5, head = [3,0,2,6,8,1,7,9,4,2,5,5,0]
[[3,0,2,6,8],[5,0,-1,-1,1],[5,2,4,9,7]]
The diagram above shows how the values are printed in the matrix. Note that the remaining spaces in the matrix are filled with -1.
m = 1, n = 4, head = [0,1,2]
[[0,1,2,-1]]
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
