<p>You are given two integers <code>m</code> and <code>n</code>, which represent the dimensions of a matrix.</p>
|
|
|
|
<p>You are also given the <code>head</code> of a linked list of integers.</p>
|
|
|
|
<p>Generate an <code>m x n</code> matrix that contains the integers in the linked list presented in <strong>spiral</strong> order <strong>(clockwise)</strong>, starting from the <strong>top-left</strong> of the matrix. If there are remaining empty spaces, fill them with <code>-1</code>.</p>
|
|
|
|
<p>Return <em>the generated matrix</em>.</p>

<pre>
|
|
<strong>Input:</strong> m = 3, n = 5, head = [3,0,2,6,8,1,7,9,4,2,5,5,0]
|
|
<strong>Output:</strong> [[3,0,2,6,8],[5,0,-1,-1,1],[5,2,4,9,7]]
|
|
<strong>Explanation:</strong> The diagram above shows how the values are printed in the matrix.
|
|
Note that the remaining spaces in the matrix are filled with -1.

<strong>Input:</strong> m = 1, n = 4, head = [0,1,2]
|
|
<strong>Output:</strong> [[0,1,2,-1]]
|
