{ "data": { "question": { "questionId": "648", "questionFrontendId": "648", "categoryTitle": "Algorithms", "boundTopicId": 1810, "title": "Replace Words", "titleSlug": "replace-words", "content": "

In English, we have a concept called root, which can be followed by some other word to form another longer word - let's call this word successor. For example, when the root "an" is followed by the successor word "other", we can form a new word "another".

\n\n

Given a dictionary consisting of many roots and a sentence consisting of words separated by spaces, replace all the successors in the sentence with the root forming it. If a successor can be replaced by more than one root, replace it with the root that has the shortest length.

\n\n

Return the sentence after the replacement.

\n\n

 

\n

Example 1:

\n\n
\nInput: dictionary = ["cat","bat","rat"], sentence = "the cattle was rattled by the battery"\nOutput: "the cat was rat by the bat"\n
\n\n

Example 2:

\n\n
\nInput: dictionary = ["a","b","c"], sentence = "aadsfasf absbs bbab cadsfafs"\nOutput: "a a b c"\n
\n\n

\n\n\n", "translatedTitle": "单词替换", "translatedContent": "

在英语中，我们有一个叫做 词根(root) 的概念，可以词根后面添加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)。

\n\n

现在，给定一个由许多词根组成的词典 dictionary 和一个用空格分隔单词形成的句子 sentence。你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。

\n\n

你需要输出替换之后的句子。

\n\n

 

\n\n

示例 1：

\n\n
\n输入：dictionary = [\"cat\",\"bat\",\"rat\"], sentence = \"the cattle was rattled by the battery\"\n输出：\"the cat was rat by the bat\"\n
\n\n

示例 2：

\n\n
\n输入：dictionary = [\"a\",\"b\",\"c\"], sentence = \"aadsfasf absbs bbab cadsfafs\"\n输出：\"a a b c\"\n
\n\n
