318. 最大单词长度乘积
给定一个字符串数组 words,找到 length(word[i]) * length(word[j]) 的最大值,并且这两个单词不含有公共字母。你可以认为每个单词只包含小写字母。如果不存在这样的两个单词,返回 0。
示例 1:
输入: [“abcw”,“baz”,“foo”,“bar”,“xtfn”,“abcdef”]
输出: 16
解释: 这两个单词为 “abcw”, “xtfn”。
示例 2:
输入: [“a”,“ab”,“abc”,“d”,“cd”,“bcd”,“abcd”]
输出: 4
解释: 这两个单词为 “ab”, “cd”。
示例 3:
输入: [“a”,“aa”,“aaa”,“aaaa”]
输出: 0
解释: 不存在这样的两个单词。
提示:
2 <= words.length <= 1000
1 <= words[i].length <= 1000
words[i] 仅包含小写字母
