<p>You are given two string arrays, <code>queries</code> and <code>dictionary</code>. All words in each array comprise of lowercase English letters and have the same length.</p>

<p>In one <strong>edit</strong> you can take a word from <code>queries</code>, and change any letter in it to any other letter. Find all words from <code>queries</code> that, after a <strong>maximum</strong> of two edits, equal some word from <code>dictionary</code>.</p>

<p>Return<em> a list of all words from </em><code>queries</code><em>, </em><em>that match with some word from </em><code>dictionary</code><em> after a maximum of <strong>two edits</strong></em>. Return the words in the <strong>same order</strong> they appear in <code>queries</code>.</p>

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

<pre>
<strong>Input:</strong> queries = [&quot;word&quot;,&quot;note&quot;,&quot;ants&quot;,&quot;wood&quot;], dictionary = [&quot;wood&quot;,&quot;joke&quot;,&quot;moat&quot;]
<strong>Output:</strong> [&quot;word&quot;,&quot;note&quot;,&quot;wood&quot;]
<strong>Explanation:</strong>
- Changing the &#39;r&#39; in &quot;word&quot; to &#39;o&#39; allows it to equal the dictionary word &quot;wood&quot;.
- Changing the &#39;n&#39; to &#39;j&#39; and the &#39;t&#39; to &#39;k&#39; in &quot;note&quot; changes it to &quot;joke&quot;.
- It would take more than 2 edits for &quot;ants&quot; to equal a dictionary word.
- &quot;wood&quot; can remain unchanged (0 edits) and match the corresponding dictionary word.
Thus, we return [&quot;word&quot;,&quot;note&quot;,&quot;wood&quot;].
</pre>

<p><strong class="example">Example 2:</strong></p>

<pre>
<strong>Input:</strong> queries = [&quot;yes&quot;], dictionary = [&quot;not&quot;]
<strong>Output:</strong> []
<strong>Explanation:</strong>
Applying any two edits to &quot;yes&quot; cannot make it equal to &quot;not&quot;. Thus, we return an empty array.

<p><strong>Constraints:</strong></p>

<ul>
	<li><code>1 &lt;= queries.length, dictionary.length &lt;= 100</code></li>

	<li><code>1 &lt;= n &lt;= 100</code></li>
	<li>All <code>queries[i]</code> and <code>dictionary[j]</code> are composed of lowercase English letters.</li>
