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

use std::io;

fn main() {
    let s = {
        let mut s = String::new();
        io::stdin().read_line(&mut s).unwrap();
        s.trim_right().to_owned()
    };
   let (a, b, c) = {
        let mut ws = s.split_whitespace();
        let a: i32 = ws.next().unwrap().parse().unwrap();
        let b: i32 = ws.next().unwrap().parse().unwrap();
        let c: i32 = ws.next().unwrap().parse().unwrap();
        (a, b, c)
    };
    match (a, b, c) {
        (5, 7, 5) => print!("YES"),
        (7, 5, 5) => print!("YES"),
        (5, 5, 7) => print!("YES"),
        _ => print!("NO"),
    }
}
