Remove 'yt' at Index 1

Write a C# Sharp program to check whether a string 'yt' appears at index 1 in a given string. If it appears return a string without 'yt' otherwise return the original string.

C# Sharp: Basic Algorithm Exercises - Check if a string 'yt' appears at index 1 in a given string.

Sample Solution:

C# Sharp Code:

using System;

// Namespace declaration
namespace exercises
{
    // Class declaration
    class Program
    {
        // Main method - entry point of the program
        static void Main(string[] args)
        {
            // Displaying the output of the 'test' method with different strings
            Console.WriteLine(test("Python")); // Output: Pyhon
            Console.WriteLine(test("ytade"));  // Output: yade
            Console.WriteLine(test("jsues"));  // Output: jsues
            Console.ReadLine();               // Keeping the console window open
        }

        // Method to perform a specific operation on the input string
        public static string test(string str)
        {
            // Check if substring from index 1 to index 2 (exclusive) is "yt"
            // If true, remove characters at index 1 and 2 from the string; otherwise, return the original string
            return str.Substring(1, 2).Equals("yt") ? str.Remove(1, 2) : str;
        }
    }
}

Sample Output:

Phon
ytade
jsues
