<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 < i < 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>"dacb"</code> is an anagram of <code>"abdc"</code>.</p> <p> </p> <p><strong class="example">Example 1:</strong></p> <pre> <strong>Input:</strong> words = ["abba","baba","bbaa","cd","cd"] <strong>Output:</strong> ["abba","cd"] <strong>Explanation:</strong> One of the ways we can obtain the resultant array is by using the following operations: - Since words[2] = "bbaa" and words[1] = "baba" are anagrams, we choose index 2 and delete words[2]. Now words = ["abba","baba","cd","cd"]. - Since words[1] = "baba" and words[0] = "abba" are anagrams, we choose index 1 and delete words[1]. Now words = ["abba","cd","cd"]. - Since words[2] = "cd" and words[1] = "cd" are anagrams, we choose index 2 and delete words[2]. Now words = ["abba","cd"]. We can no longer perform any operations, so ["abba","cd"] is the final answer.</pre> <p><strong class="example">Example 2:</strong></p> <pre> <strong>Input:</strong> words = ["a","b","c","d","e"] <strong>Output:</strong> ["a","b","c","d","e"] <strong>Explanation:</strong> No two adjacent strings in words are anagrams of each other, so no operations are performed.</pre> <p> </p> <p><strong>Constraints:</strong></p> <ul> <li><code>1 <= words.length <= 100</code></li> <li><code>1 <= words[i].length <= 10</code></li> <li><code>words[i]</code> consists of lowercase English letters.</li> </ul>
