给你一个下标从 0 开始的字符串 words ，其中 words[i] 由小写英文字符组成。 在一步操作中，需要选出任一下标 i ，从 words 中 删除 words[i] 。其中下标 i 需要同时满足下述两个条件：

You are given a 0-indexed string array words, where words[i] consists of lowercase English letters. In one operation, select any index i such that 0 < i < words.length and words[i - 1] and words[i] are anagrams, and delete words[i] from words. Keep performing…
