Codeforces 1791A Codeforces Checking Solution & Explanation

Difficulty : 800

Problem Description

Given a lowercase Latin character (letter), check if it appears in the string codeforces.

Input

The first line of the input contains an integer t (1≤t≤26) — the number of test cases.

The only line of each test case contains a character c — a single lowercase Latin character (letter).

Output

For each test case, output “YES” (without quotes) if c satisfies the condition, and “NO” (without quotes) otherwise.

You can output the answer in any case (for example, the strings “yEs”, “yes”, “Yes” and “YES” will be recognized as a positive answer).

Examples

Solution

The question assesses your ability to utilize the string.Contains method, recognizing that other languages may use different methods for the same purpose, such as array-based approaches.

C# Solution

Solution1

int t = int.Parse(Console.ReadLine());
string str = "codeforces";

for(int i=0; i<t; i++){
    var c = Console.ReadLine();
    Console.WriteLine(str.Contains(c)?"YES":"NO");
}
