<p>Given an integer n, return <em>the <strong>largest palindromic integer</strong> that can be represented as the product of two <code>n</code>-digits integers</em>. Since the answer can be very large, return it <strong>modulo</strong> <code>1337</code>.</p>

<p>&nbsp;</p>
<p><strong>Example 1:</strong></p>

<pre>
<strong>Input:</strong> n = 2
<strong>Output:</strong> 987
Explanation: 99 x 91 = 9009, 9009 % 1337 = 987
</pre>

<p><strong>Example 2:</strong></p>

<pre>
<strong>Input:</strong> n = 1
<strong>Output:</strong> 9
</pre>
