Note:&nbsp;This problem is slightly different from the original one the book.

Example:

<pre>
Input: <code>[&quot;eat&quot;, &quot;tea&quot;, &quot;tan&quot;, &quot;ate&quot;, &quot;nat&quot;, &quot;bat&quot;]</code>,

 [&quot;ate&quot;,&quot;eat&quot;,&quot;tea&quot;],
 [&quot;nat&quot;,&quot;tan&quot;],
 [&quot;bat&quot;]
]</pre>

<ul>
	<li>All inputs will be in lowercase.</li>
	<li>The order of your output does not&nbsp;matter.</li>
</ul>
