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

use std::io::Read;
fn main() {
    let mut line = vec![];
    drop(std::io::stdin().read_to_end(&mut line));
    line = line.iter().map(|x|*x).filter(|x| (*x as char).is_digit(10)).collect();
    line.sort();
    print!("{:?}", line);
    print!("{}", if line == ['5' as u8,'5' as u8,'7' as u8] { "YES" } else { "NO" });
}
