<p>Given a <code>sentence</code> that consists of some words separated by a <strong>single space</strong>, and a <code>searchWord</code>, check if <code>searchWord</code> is a prefix of any word in <code>sentence</code>.</p>

<p>Return <em>the index of the word in </em><code>sentence</code><em> (<strong>1-indexed</strong>) where </em><code>searchWord</code><em> is a prefix of this word</em>. If <code>searchWord</code> is a prefix of more than one word, return the index of the first word <strong>(minimum index)</strong>. If there is no such word return <code>-1</code>.</p>
