Sample Solution:-

C# Sharp Code:

using System;
namespace exercises
{
   class Program
    {       
        static void Main(string[] args)
        {
            Console.WriteLine(test("abab"));
            Console.WriteLine(test("abcdef"));
            Console.WriteLine(test("xyzsderxy"));
            Console.ReadLine();
        }

 public static bool test(string s1) 
        {
           return s1.Substring(0, 2) == s1.Substring(s1.Length - 2);
        }
   }
}

Sample Output:

True

Previous: Write a C# Sharp program to check if a given string begins with "abc" or "xyz". If the string begins with "abc" or "xyz" return "abc" or "xyz" otherwise return the empty string.
Next: Write a C# Sharp program to concate two given strings. If the given strings have different length remove the characters from the longer string.
