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

use std::io;
use std::io::prelude::*;

fn run(args: &Vec<String>) -> bool {
    let mut s: Vec<u32> = args[0].split(' ').map(|s| s.parse().unwrap()).collect();
    s.sort();
    s[0] == 5 && s[1] == 5 && s[2] == 7
}

fn main() {
    let stdin = io::stdin();
    let args = stdin.lock().lines().map(|l| l.unwrap()).collect();
    let r = run(&args);
    println!("{}", if r { "YES" } else { "NO" });
}
