import java.util.Scanner;

public class Bitset {
  public static void main(String[] args) {//直接調用Integer.toBinaryString(int i)
    Scanner sc=new Scanner(System.in);  //以二進制无符号整数返回一个整数参数的字符串形式
    while(sc.hasNext()){
      int n=sc.nextInt();
      System.out.println(Integer.toBinaryString(n));
    }
