public class Converter{
public static String toBinary(int num){
/*String binary="";
while(num>0){
binary = (num%2) + binary;
num /=2;
}*/
return Integer.toBinaryString(num);

}
}

public class Program {
public static void main(String[ ] args) {
Scanner sc = new Scanner(System.in);
int x = sc.nextInt();
System.out.print(Converter.toBinary(x));
}
}

//It works
