use std :: io ;
fn main(){
 loop{  
    let mut no = String::new();

  io :: stdin()
    .read_line(&mut no)
    .expect("failed to read line ");

 let no : i32 = no.trim().parse().expect("error!");

if no == 0 {
    println!("1");
 } else if no == 1 {
        println!("0");
    }else {
        println!("...");
    }
}
