public class Solution extends Object
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.
