import java.util.Scanner;

// 注意类名必须为 Main, 不要有任何 package xxx 信息
public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        while(sc.hasNext()){
            String s = sc.next();
		    String类型转换到StringBuilder类型
            StringBuilder sb = new StringBuilder();
            sb.append(s);
		    补零
            int size = sb.length();
            int addZero = 8 - size%8;
            while((addZero > 0) && (addZero < 8)){
                sb.append("0");
                addZero --;
            }
		    StringBuilder类型转换为String类型
            String str1 = sb.toString();
            while(str1.length() > 0){
                System.out.println(str1.substring(0,8));
                str1 = str1.substring(8);
            }
        }
        
    }
