1684 - Count the Number of Consistent Strings.

Easy

You are given a string allowed consisting of distinct characters and an array of strings words. A string is consistent if all characters in the string appear in the string allowed.

Return the number of consistent strings in the array words.

Example 1:

Input: allowed = “ab”, words = [“ad”,“bd”,“aaab”,“baa”,“badab”]

Output: 2

Explanation: Strings “aaab” and “baa” are consistent since they only contain characters ‘a’ and ‘b’.

Example 2:

Input: allowed = “abc”, words = [“a”,“b”,“c”,“ab”,“ac”,“bc”,“abc”]

Output: 7

Explanation: All strings are consistent.

Example 3:

Input: allowed = “cad”, words = [“cc”,“acd”,“b”,“ba”,“bac”,“bad”,“ac”,“d”]

Output: 4

Explanation: Strings “cc”, “acd”, “ac”, and “d” are consistent.

Constraints:

  • 1 <= words.length <= 104
  • 1 <= allowed.length <= 26
  • 1 <= words[i].length <= 10
  • The characters in allowed are distinct.
  • words[i] and allowed contain only lowercase English letters.
