    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.
