All other keys on the keyboard work properly.</p>
+
+<p>Given a string <code>text</code> of words separated by a single space (no leading or trailing spaces) and a string <code>brokenLetters</code> of all <strong>distinct</strong> letter keys that are broken, return <em>the <strong>number of words</strong> in</em> <code>text</code> <em>you can fully type using this keyboard</em>.</p>

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