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)
        {
            // Calling the 'test' method with different strings and integers and displaying the returned values
            Console.WriteLine(test("Python", 1));  // Output: "Pyton"
            Console.WriteLine(test("Python", 0));  // Output: "ython"
            Console.WriteLine(test("Python", 4));  // Output: "Pytho"
            Console.ReadLine();                   // Keeping the console window open
        }

        // Method to remove a character at a specified index 'n' from the input string 'str'
        public static string test(string str, int n)
        {
            return str.Remove(n, 1);  // Removing the character at index 'n' and returning the modified string
        }
   }
}

Sample Output:

Pthon
ython
Pythn
