给定一个字符串数组 words,请计算当两个字符串 words[i] 和 words[j] 不包含相同字符时,它们长度的乘积的最大值。假设字符串中只包含英语的小写字母。如果没有不包含相同字符的一对字符串,返回 0。
words
words[i]
words[j]
示例 1:
输入:words = ["abcw","baz","foo","bar","fxyz","abcdef"] 输出:16 解释:这两个单词为 "abcw", "fxyz"。它们不包含相同字符,且长度的乘积最大。
示例 2:
输入:words = ["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:words = ["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
