c#-da belə yazdım. 100% using System; namespace ConsoleApp1 { class Program { static void Main() { string n = Console.ReadLine(); int say = 0; int len = n.Length; int orta = 0; if (len % 2 == 0) orta = len / 2; else { orta = (len - 1) / 2; say = 1; }

        for (int i = 0; i < orta; i++)
        {
            string sol = n.Substring(i, 1);
            string sag = n.Substring(len - 1 - i, 1);
            if (sol == sag)
                say++;
        }
        Console.WriteLine(say);
        Console.ReadKey();
    }
}

}
