<p>You are given a <strong>0-indexed</strong> string array <code>words</code>, where <code>words[i]</code> consists of lowercase English letters.</p>

<p>In one operation, select any index <code>i</code> such that <code>0 &lt; i &lt; words.length</code> and <code>words[i - 1]</code> and <code>words[i]</code> are <strong>anagrams</strong>, and <strong>delete</strong> <code>words[i]</code> from <code>words</code>. Keep performing this operation as long as you can select an index that satisfies the conditions.</p>

<p>Return <code>words</code> <em>after performing all operations</em>. It can be shown that selecting the indices for each operation in <strong>any</strong> arbitrary order will lead to the same result.</p>

<p>An <strong>Anagram</strong> is a word or phrase formed by rearranging the letters of a different word or phrase using all the original letters exactly once. For example, <code>&quot;dacb&quot;</code> is an anagram of <code>&quot;abdc&quot;</code>.</p>

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

<pre>
<strong>Input:</strong> words = [&quot;abba&quot;,&quot;baba&quot;,&quot;bbaa&quot;,&quot;cd&quot;,&quot;cd&quot;]
<strong>Output:</strong> [&quot;abba&quot;,&quot;cd&quot;]
<strong>Explanation:</strong>
One of the ways we can obtain the resultant array is by using the following operations:
- Since words[2] = &quot;bbaa&quot; and words[1] = &quot;baba&quot; are anagrams, we choose index 2 and delete words[2].
  Now words = [&quot;abba&quot;,&quot;baba&quot;,&quot;cd&quot;,&quot;cd&quot;].
- Since words[1] = &quot;baba&quot; and words[0] = &quot;abba&quot; are anagrams, we choose index 1 and delete words[1].
  Now words = [&quot;abba&quot;,&quot;cd&quot;,&quot;cd&quot;].
- Since words[2] = &quot;cd&quot; and words[1] = &quot;cd&quot; are anagrams, we choose index 2 and delete words[2].
  Now words = [&quot;abba&quot;,&quot;cd&quot;].
We can no longer perform any operations, so [&quot;abba&quot;,&quot;cd&quot;] is the final answer.</pre>

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

<pre>
<strong>Input:</strong> words = [&quot;a&quot;,&quot;b&quot;,&quot;c&quot;,&quot;d&quot;,&quot;e&quot;]
<strong>Output:</strong> [&quot;a&quot;,&quot;b&quot;,&quot;c&quot;,&quot;d&quot;,&quot;e&quot;]
<strong>Explanation:</strong>
No two adjacent strings in words are anagrams of each other, so no operations are performed.</pre>
