HOW TO FIND DIFFERENCES BETWEEN TWO STRINGS ?

Open console Application 

CODE:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace ConsoleApplication1

{

    class Program

    {

     

            public void testmethod(string str1, string str2)

            {

                string Op1 = str1;

                string Op2 = str2;

                foreach (char character in str2.ToCharArray())

                {

                    Op1 = Op1.Replace(character.ToString(), "");

                }

                foreach (char character in str1.ToCharArray())

                {

                    Op2 = Op2.Replace(character.ToString(), "");

                }

     Console.WriteLine("all Characters which is present in str1 and not in str2:{0}", Op1);

     Console.WriteLine("all Characters which is present in str2 and not in str1:{0}", Op2);

            }

             static void Main(string[] args)

             {

               string str1 = Convert.ToString(Console.ReadLine());

               string str2 = Convert.ToString(Console.ReadLine());

                 Program p = new Program();

                 p.testmethod(str1,str2);

                 Console.ReadLine();

             }

           

    }

}

OUTPUT:

DESCRIPTION:

In op1(First operation str1-str2 is happening like …VAMSI-IA=VMS)…

VAMSI:VMS//   ” I” and “A” IN SECOND STRING

In op2 (Second operation str2-str1 is happening like… INDLA-IA=NDL)

INDLA:NDL// ” I” and “A” IN FIRST STRING
