<p><strong>Example 1:</strong></p>

<pre>
<strong>Input:</strong> words = [&quot;aaaa&quot;,&quot;asas&quot;,&quot;able&quot;,&quot;ability&quot;,&quot;actt&quot;,&quot;actor&quot;,&quot;access&quot;], puzzles = [&quot;aboveyz&quot;,&quot;abrodyz&quot;,&quot;abslute&quot;,&quot;absoryz&quot;,&quot;actresz&quot;,&quot;gaswxyz&quot;]
<strong>Output:</strong> [1,1,3,2,4,0]
<strong>Explanation:</strong> 
1 valid word for &quot;aboveyz&quot; : &quot;aaaa&quot; 
1 valid word for &quot;abrodyz&quot; : &quot;aaaa&quot;
