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);
// 注意 hasNext 和 hasNextLine 的区别
String str = in.nextLine();
int lineLength = 8;
// 计算需要处理的总长度
int totalLength = ((str.length() + lineLength - 1) /
lineLength) * lineLength;
// 补充‘0’直到长度为8的倍数
StringBuilder sb = new StringBuilder(str);
while(sb.length() < totalLength) {
sb.append('0');
}
// 每8个字符输出一行
for(int i = 0; i < sb.length(); i += lineLength) {
System.out.println(sb.substring(i, i + lineLength));
}
}
