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 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"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"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.
Constraints
- 1 <= sentence.length <= 100
- 1 <= searchWord.length <= 10
- sentence consists of lowercase English letters and spaces.
- searchWord consists of lowercase English letters.
