1 \le K \le 500

1 \le h_i \le 500

All values in input are integers.

Input

Input is given from Standard Input in the following format:

N K
h_1 h_2 \ldots h_N

use std::io;
use std::str::FromStr;

fn input_int_tuple() -> (i32, i32) {
  let mut line: String = String::new();
  io::stdin().read_line(&mut line);
  let vec: Vec<i32> = line.split_whitespace().map(|s| s.parse().unwrap()).collect();
  (vec[0], vec[1])
}

fn input_i32_vec() -> Vec<i32> {
  let mut line: String = String::new();
  io::stdin().read_line(&mut line);
  line.split_whitespace().map(|s| s.parse().unwrap()).collect()
}

fn main() {
  let (n, k) = input_int_tuple();
  let h_vec = input_i32_vec();
  let mut sum = 0;
  for h in h_vec {
    if h >= k {
      sum += 1;
    }
  }
