<p>You are given a string <code>s</code> and a pattern string <code>p</code>, where <code>p</code> contains <strong>exactly one</strong> <code>&#39;*&#39;</code> character.</p>

<p>The <code>&#39;*&#39;</code> in <code>p</code> can be replaced with any sequence of zero or more characters.</p>

<p>Return <code>true</code> if <code>p</code> can be made a <span data-keyword="substring-nonempty">substring</span> of <code>s</code>, and <code>false</code> otherwise.</p>

<p>&nbsp;</p>
<p><strong class="example">Example 1:</strong></p>
