    class Program
    {
        static void Main(string[] args)
        {
            int[] arr = new int[5];

            arr[0] = 13;
            arr[1] = 3;

            index = Array.IndexOf<int>(arr, 180);
            Console.WriteLine(index);

            index = Array.LastIndexOf(arr, 200);
            Console.WriteLine(index);
        }
    }
