Output: &quot;s&#39;teL ekat edoCteeL tsetnoc&quot;
</pre>

Example 2:

<pre>
Input: s = &quot;Mr Ding&quot;
Output: &quot;rM gniD&quot;
</pre>

&nbsp;
Constraints:

<ul>
	<li><code>1 &lt;= s.length &lt;= 5 * 104</code></li>
	<li><code>s</code> contains printable ASCII characters.</li>
	<li><code>s</code> does not contain any leading or trailing spaces.</li>
	<li>There is at least one word in <code>s</code>.</li>
	<li>All the words in <code>s</code> are separated by a single space.</li>
