using System;
class Program
{
    static void Main(string[] args)
    {
        // スペース区切りの整数の入力
        string[] input = Console.ReadLine().Split(' ');
        int n = int.Parse(input[0]);
        int k = int.Parse(input[1]);
        int[] d = new int[n];

        input = Console.ReadLine().Split(' ');

        for(int i = 0; i < n; i++)
        {
            d[i] = int.Parse(input[i]);
        }

        int cnt = 0;
        for (int i = 0; i < n; i++)
        {
            if (d[i] >= k)
            {
                cnt++;
            }
        }
        Console.WriteLine(cnt);
