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
Inputsentence = "i love eating burger", searchWord = "burg"
Output4
"burg" is prefix of "burger" which is the 4th word in the sentence.
Example 2
Inputsentence = "this problem is an easy problem", searchWord = "pro"
Output2
"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.
