1961 - Check If String Is a Prefix of Array\. Easy Given a string `s` and an array of strings `words`, determine whether `s` is a **prefix string** of `words`. A string `s` is a **prefix string** of `words` if `s` can be made by concatenating the first `k` strings in `words` for some **positive** `k` no larger than `words.length`. Return `true` _if_ `s` _is a **prefix string** of_ `words`_, or_ `false` _otherwise_. **Example 1:** **Input:** s = "iloveleetcode", words = ["i","love","leetcode","apples"] **Output:** true **Explanation:** s can be made by concatenating "i", "love", and "leetcode" together. **Example 2:** **Input:** s = "iloveleetcode", words = ["apples","i","love","leetcode"] **Output:** false **Explanation:** It is impossible to make s using a prefix of arr. **Constraints:** * `1 <= words.length <= 100` * `1 <= words[i].length <= 20` * `1 <= s.length <= 1000` * `words[i]` and `s` consist of only lowercase English letters.
