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 in = new Scanner(System.in);
        String str = "";
        if (in.hasNext()) {
            str = in.next().toString();
        }

        int n = 8;
        //先补0
        int a = str.length() % n;
        if (a > 0) {
            StringBuilder add0 = new StringBuilder();
            while (a < n) {
                add0.append("0");
                a++;
            }
            str += add0.toString();
        }
      //  System.out.println(str);
        for (int i = 0; i < str.length(); i += n) {
            System.out.println(str.substring(i, i+n));
        }
    }
}

1、先获取输入的字符串

2、再和8求余，判断要补几个0

3、再按8位换行打印
