using System;
class Program
{
    static void Main(string[] args)
    {
        //// 整数の入力
        //int a = int.Parse(Console.ReadLine());
        //// スペース区切りの整数の入力
        //string[] input = Console.ReadLine().Split(' ');
        //int b = int.Parse(input[0]);
        //int c = int.Parse(input[1]);
        //// 文字列の入力
        //string s = Console.ReadLine();
        ////出力
        //Console.WriteLine((a + b + c) + " " + s);

        string[] input = Console.ReadLine().Split(' ');
        int b = int.Parse(input[0]);
        int c = int.Parse(input[1]);

        int count = 0;
        string[] H = Console.ReadLine().Split(' ');
        foreach(var h in H)
        {
            if ( int.Parse(h) >= c)
            {
                count++;
            }
        }

        Console.WriteLine(count);
    }
