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:

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:

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:

• <code>1 <= m, n <= 10⁵</code>

• <code>1 <= m * n <= 10⁵</code>

• The number of nodes in the list is in the range [1, m * n].

• 0 <= Node.val <= 1000
