Problem Statement:

Input :- "1-2-3-4-5"
O/P:- Consecutive

Input :- "5-4-3-2-1"
O/P:- Consecutive

Input :- "1-4-3-2-5"
O/P:- Not Consecutive


Program

 using System;  
 using System.Collections.Generic;  
 using System.Linq;  
 using System.Text;  
 namespace Cosecutive  
 {  
   class ConsecutiveClass  
   {  
     static void Main(string[] args)  
     {  
       string s = "1-2-3-4-5-6";  
       List<string> numbers = s.Split('-').ToList();  
       int hyphenCount = s.ToCharArray().Count(x => x == '-');  
       int distinctNumCnt=numbers.Distinct().Count();  
       int listMaxLen = distinctNumCnt - 1;  
       int loopcount=0;  
       if ((hyphenCount + 1) == distinctNumCnt)  
       {  
         for (int i = 0; i < numbers.Count/2; i++)  
         {  
           if (Math.Abs(Convert.ToInt32(numbers[listMaxLen - i]) - Convert.ToInt32(numbers[i])) + 1 == distinctNumCnt)  
           {  
             distinctNumCnt -= 2;  
             loopcount++;  
           }  
           else  
           {  
             Console.WriteLine("Not Consecutive");  
             break;  
           }  
         }  
         if (loopcount == numbers.Count / 2)  
           Console.WriteLine("Consecutive");  
       }  
       else  
         Console.WriteLine("Not Consecutive");  
       Console.ReadLine();  
     }  
   }  
 }
