Replace Words
In English, we have a concept called root, which can be followed by some other word to form another longer word called a derivative. For example, when the root "help" is followed by the word "ful", we can form a derivative "helpful".
Given a dictionary consisting of many roots and a sentence consisting of words separated by spaces, replace all the derivatives in the sentence with the root forming it. If a derivative 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"The derivatives "cattle", "rattled", and "battery" are replaced by their shortest matching roots "cat", "rat", and "bat".
Example 2
Input
dictionary = ["a","b","c"], sentence = "aadsfasf absbs bbab cadsfafs"Output
"a a b c"Each word is replaced by the shortest root from the dictionary that is its prefix.
Constraints

- 1 <= dictionary[i].length <= 100
- dictionary[i] consists of only lower-case letters.
- 1 <= sentence.length <= 10^6
- sentence consists of only lower-case letters and spaces.
- The number of words in sentence is in the range [1, 1000]
- The length of each word in sentence is in the range [1, 1000]
- Every two consecutive words in sentence will be separated by exactly one space.
- sentence does not have leading or trailing spaces.
