CODE:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Front
{
    class Program
    {
        static void Main(string[] args)
        {
            string inputStr;// the string to be used as input
            string chars;// the string that holds the first three characters of the input string
            Console.WriteLine("Enter a string:");// prompt to enter a string
            inputStr = Console.ReadLine();// reading a string
            if ((inputStr.Trim().Length < 3))// checking the length of the input string
            {
                Console.WriteLine("Enter a valid string of length at least 3 characters..");
            }
            else
            {
                chars = inputStr.Substring(0, 3);// get the first three chars of the input string
                inputStr = chars + inputStr + chars;// appending the chars at the front and the back of the string
          
            }
            Console.WriteLine(inputStr);// writing the output string
            Console.ReadLine();// to hold the output window
        }
    }
}

OUTPUT:
