Sample Solution:-

C# Sharp Code:

using System;

namespace exercises
{
   class Program
    {       
        static void Main(string[] args)
        {
            Console.WriteLine(test("abc"));
            Console.WriteLine(test("abcdef"));
            Console.WriteLine(test("C"));
            Console.WriteLine(test("xyz"));
            Console.WriteLine(test("xyzsder"));
            Console.ReadLine();
        }

 public static string test(string s1) 
        {
          if (s1.StartsWith("abc"))
            {
                return "abc";
            }
            else if (s1.StartsWith("xyz"))
            {
                return "xyz";
            }
            else
            {
                return String.Empty;
            }
        }
   }
}

Sample Output:

abc
abc

xyz
xyz
