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

fn read() -> (i32, i32, i32) {
    let mut s = String::new();
    std::io::stdin().read_line(&mut s).unwrap();
    let mut vec: Vec<i32> = s
        .trim()
        .split_whitespace()
        .map(|x| x.parse().unwrap())
        .collect();
    vec.sort();
    (vec[0], vec[1], vec[2])
}

fn main() {
    let (a, b, c) = read();
    match (a, b, c) == (5, 5, 7) {
        true => println!("YES"),
        false => println!("NO"),
    };
}
