Solution in Rust (1.15.1) (judge verdict: Wrong Answer)

fn main() {
    let scan = std::io::stdin();

    let mut line = String::new();

    let _ = scan.read_line(&mut line);

    let n:i32 = line.trim().parse().unwrap();

    let ans : &str =  if n/10==9 || n%10==9 { "YES" } else { "NO" };
    println!("{}",ans);
}
