        {
            Print();
            Console.ReadKey();
        }

        /// <summary>
        /// Print any word with this format . Example : ABC - 
        /// Output--> ABC , AB , C , BC , B , C - Replace ',' with new Line
        /// </summary>
        private static void Print()
        {
            Console.Write("Enter a string : ");
            string result = Console.ReadLine();
            
            while (result.Length > 0)
            {
                string temp = result;
                while (temp.Length > 0)
                {
                    Console.WriteLine(temp);
                    temp = temp.Remove(temp.Length - 1);
                }
                Console.WriteLine("------------------------------");
                result = result.Remove(0, 1);
            }
        }
    }
}
