Solution in C# (judge verdict: Runtime Error)

using System;

namespace ConsoleApplication{
    public class Program{
        public static void Main(string[] args){
            string ring = Console.ReadLine();
            string keyword = Console.ReadLine();

            int len = ring.Length / 2 +1;
            string ring2 = ring.Substring(keyword.Length/2, len) + ring + ring.Substring(0,len);

            if(ring2.IndexOf(keyword) != -1){
                Console.WriteLine("Yes");
            }else{
                Console.WriteLine("No");
            }
        }
    }
}
