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

use std::io;

fn main() {
    let N=get_int();
    match N {
        3|5|7 => println!("YES"),
        other => println!("NO"),
    }
}

fn get_String()->String{
    let mut s =String::new();
    io::stdin().read_line(&mut s).expect("Fail!");        
    s.trim().to_string()
}

fn get_int()->i32{
    let mut input =String::new();
    io::stdin().read_line(&mut input).expect("Fail!");
    input.trim().to_string().parse().unwrap()
}
