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 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.

class Solution {
    fun isPrefixOfWord(sentence: String, searchWord: String): Int {
        val words = sentence.split(" ")
        for ((index, word) in words.withIndex()) {
            if (word.startsWith(searchWord)) {
                return index + 1
            }
        }
        return -1
    }
}
