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.

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
