    1455 - Check If a Word Occurs As a Prefix of Any Word in a Sentence\.

    Easy

    Given a sentence that consists of some words separated by a single space , and a searchWord, check if searchWord is a prefix of any word in sentence.

    Return the index of the word in sentence ( 1-indexed ) where searchWord is a prefix of this word. If searchWord is a prefix of more than one word, return the index of the first word (minimum index). If there is no such word return -1.

    A prefix of a string s is any leading contiguous substring of s.

    Example 1:

    Input: sentence = "i love eating burger", searchWord = "burg"

    Output: 4

    Explanation: "burg" is prefix of "burger" which is the 4th word in the sentence.

    Example 2:

    Input: sentence = "this problem is an easy problem", searchWord = "pro"

    Output: 2

    Explanation: "pro" is prefix of "problem" which is the 2nd and the 6th word in the sentence, but we return 2 as it's the minimal index.

    Example 3:

    Input: sentence = "i am tired", searchWord = "you"

    Output: -1

    Explanation: "you" is not a prefix of any word in the sentence.

    Constraints:

    • 1 <= sentence.length <= 100

    • 1 <= searchWord.length <= 10

    • sentence consists of lowercase English letters and spaces.

    • searchWord consists of lowercase English letters.
