Solution in Rust (1.15.1) (judge verdict: Accepted)

fn main() {
    let (n, k) = {
        let mut line = String::new();
        std::io::stdin().read_line(&mut line);
        let ns: Vec<i64> = line.split_whitespace().map(|a|a.parse().unwrap()).collect();
        (ns[0], ns[1])
    };
    let h: Vec<i64> = {
        let mut line = String::new();
        std::io::stdin().read_line(&mut line);
        line.split_whitespace().map(|a|a.parse().unwrap()).collect()
    };

    println!("{}", h.iter().filter(|&&a| a >= k).count());
