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

use std::io;
use std::str::FromStr;

fn main () {
    let mut s = String::new();
    io::stdin().read_line(&mut s).ok();
    let mut it = s.split_whitespace ()
        .map(|n| i64::from_str(n).unwrap ());
    let (a,b,c) = (it.next().unwrap (), it.next().unwrap (), it.next().unwrap ());
    
    if (a==5 && b==5 && c==7) ||
       (a==5 && b==7 && c==5) ||
       (a==7 && b==5 && c==5) {
        println!("YES");
    } else {
        println!("NO");
    }
}
