Replace Words
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 derivative.
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 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"
Example 2
Input: dictionary = ["a","b","c"], sentence = "aadsfasf absbs bbab cadsfafs"
Output: "a a b c"
Constraints
- 1 <= dictionary.length <= 1000
- 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.
