Given a string s and an array of strings words, determine whether s is a prefix string of words.

\n\n

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.

\n\n

Return true if s is a prefix string of words, or false otherwise.

\n\n

 

\n

Example 1:

\n\n
\nInput: s = "iloveleetcode", words = ["i","love","leetcode","apples"]\nOutput: true\nExplanation:\ns can be made by concatenating "i", "love", and "leetcode" together.\n
\n\n

Example 2:

\n\n
\nInput: s = "iloveleetcode", words = ["apples","i","love","leetcode"]\nOutput: false\nExplanation:\nIt is impossible to make s using a prefix of arr.
