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

use std::io;
fn main() {
    let mut buf = String::new();

    std::io::stdin().read_line(&mut buf).unwrap();
    let mut iter = buf.split_whitespace();
    let N: u32 = iter.next().unwrap().parse().unwrap();

    let ans = if  N%10 == 9 || (N/10)%10 == 9 { "Yes" } else { "No" };
    println!("{}",ans);
}
