剑指 Offer II 063 替换单词
在英语中,有一个叫做 词根(root)
的概念,它可以跟着其他一些词组成另一个较长的单词——我们称这个词为 继承词(successor)
。例如,词根an
,跟随着单词 other
(其他),可以形成新的单词 another
(另一个)。
现在,给定一个由许多词根组成的词典和一个句子,需要将句子中的所有继承词
用词根
替换掉。如果继承词
有许多可以形成它的词根
,则用最短的词根替换它。
需要输出替换之后的句子。
示例 1:
输入:dictionary = ["cat","bat","rat"], sentence = "the cattle was rattled by the battery" 输出:"the cat was rat by the bat"
示例 2:
输入:dictionary = ["a","b","c"], sentence = "aadsfasf absbs bbab cadsfafs" 输出:"a a b c"
示例 3:
输入:dictionary = ["a", "aa", "aaa", "aaaa"], sentence = "a aa a aaaa aaa aaa aaa aaaaaa bbb baba ababa" 输出:"a a a a a a a a bbb baba a"
示例 4:
输入:dictionary = ["catt","cat","bat","rat"], sentence = "the cattle was rattled by the battery" 输出:"the cat was rat by the bat"
示例 5:
输入:dictionary = ["ac","ab"], sentence = "it is abnormal that this solution is accepted" 输出:"it is ab that this solution is ac"
提示:
1 <= dictionary.length <= 1000
1 <= dictionary[i].length <= 100
dictionary[i]
仅由小写字母组成。1 <= sentence.length <= 10^6
sentence
仅由小写字母和空格组成。sentence
中单词的总量在范围[1, 1000]
内。sentence
中每个单词的长度在范围[1, 1000]
内。sentence
中单词之间由一个空格隔开。sentence
