1455.CheckIfaWordOccursAsaPrefixofAnyWordinaSentence.py

"""
    Given a sentence that consists of some words separated by a single space, 
    and a searchWord.
    You have to check if searchWord is a prefix of any word in sentence.
    Return the index of the word in sentence where searchWord is a prefix of 
    this word (1-indexed).
    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:
    Input: sentence = "i love eating burger", searchWord = "burg"
    Output: 4
    Explanation: "burg" is prefix of "burger" which is the 4th 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.
