Check if a String Is an Acronym of Words
Given an array of strings words and a string s, determine if s is an acronym of words.
The string s is considered an acronym of words if it can be formed by concatenating the first character of each string in words in order.
Return true if s is an acronym of words, and false otherwise.
Example 1
Input
words = ["alice","bob","charlie"], s = "abc"Output
trueThe first characters in "alice", "bob", and "charlie" are 'a', 'b', and 'c', respectively, so
s = "abc" is the acronym.Example 2
Input
words = ["an","apple"], s = "a"Output
falseThe first characters in "an" and "apple" form "aa", so
s = "a" is not the acronym.Constraints
- 1 <= words.length <= 100
- 1 <= words[i].length <= 10
- 1 <= s.length <= 100
- words[i] and s consist of lowercase English letters.
