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".
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.
Return the sentence after the replacement.
Example 1:
Input: dictionary = ["cat","bat","rat"], sentence = "the cattle was rattled by the battery" Output: "the cat was rat by the bat"
Example 2:
Input: dictionary = ["a","b","c"], sentence = "aadsfasf absbs bbab cadsfafs" Output: "a a b c"
Example 3:
Input: dictionary = ["a", "aa", "aaa", "aaaa"], sentence = "a aa a aaaa aaa aaa aaa aaaaaa bbb baba ababa" Output: "a a a a a a a a bbb baba a"
Example 4:
Input: dictionary = ["catt","cat","bat","rat"], sentence = "the cattle was rattled by the battery" Output: "the cat was rat by the bat"
Example 5:
Input: dictionary = ["ac","ab"], sentence = "it is abnormal that this solution is accepted" Output: "it is ab that this solution is ac"
Constraints:
1 <= dictionary.length <= 10001 <= dictionary[i].length <= 100dictionary[i]consists of only lower-case letters.1 <= sentence.length <= 10^6sentenceconsists of only lower-case letters and spaces.- The number of words in
sentenceis in the range[1, 1000] - The length of each word in
sentenceis in the range[1, 1000] - Each two consecutive words in
sentencewill be separated by exactly one space. sentencedoes not have leading or trailing spaces.
