use proconio::input;

fn main() {
    input! {
        n: usize,
        k: u32,
        mut h: [u32; n]
    }

    solve(k, &mut h);
}

fn solve(k: u32, h: &mut [u32]) {
    h.sort();
    h.reverse();

    for (i, x) in h.iter().enumerate() {
        if x < &k {
            println!("{}", i);
            return;
