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

fn main() {
    let mut line = String::new();
    std::io::stdin().read_line(&mut line).unwrap();

    let sum: u8 = line
        .trim()
        .split(' ')
        .map(|s| s.parse::<u8>().unwrap())
        .sum();
    if sum == 17 {
        println!("YES");
    } else {
        println!("NO");
    }
}
