| # 1455. Check If a Word Occurs As a Prefix of Any Word in a Sentence
"""
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 the 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'.
