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
Inputwords = ["alice","bob","charlie"], s = "abc"
Outputtrue
The first characters in "alice", "bob", and "charlie" are 'a', 'b', and 'c', respectively, so s = "abc" is the acronym.
Example 2
Inputwords = ["an","apple"], s = "a"
Outputfalse
The 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.
