648 - Replace Words.
Medium
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”
