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"

**Constraints:**

*   `1 <= dictionary.length <= 1000`
*   `1 <= dictionary[i].length <= 100`
*   `dictionary[i]` consists of only lower-case letters.
*   1 <= sentence.length <= 106
*   `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.
