<p>You are given a string <code>s</code> and a pattern string <code>p</code>, where <code>p</code> contains <strong>exactly two</strong> <code>'*'</code> characters.</p>
|
|
|
|
<p>The <code>'*'</code> in <code>p</code> matches any sequence of zero or more characters.</p>
|
|
|
|
<p>Return the length of the <strong>shortest</strong> <span data-keyword="substring">substring</span> in <code>s</code> that matches <code>p</code>. If there is no such substring, return -1.</p>
|
|
<strong>Note:</strong> The empty substring is considered valid.
