1455. Check If a Word Occurs As a Prefix of Any Word in a Sentence

https://leetcode.com/problems/check-if-a-word-occurs-as-a-prefix-of-any-word-in-a-sentence

Description

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
**Explanation:** "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
**Explanation:** "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.

Example 3:

**Input:** sentence = "i am tired", searchWord = "you"
**Output:** -1
**Explanation:** "you" is not a prefix of any word in the sentence.

Example 4:

**Input:** sentence = "i use triple pillow", searchWord = "pill"
**Output:** 4

Example 5:

**Input:** sentence = "hello from the other side", searchWord = "they"
**Output:** -1

Constraints:

• 1 <= sentence.length <= 100

• 1 <= searchWord.length <= 10

• sentence consists of lowercase English letters and spaces.

• searchWord consists of lowercase English letters.
