太水了不用思路，直接截取输出就是了....
AC代码：
import java.util.Scanner;
/**
* @author CC11001100
*/
public class Main {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
while (sc.hasNextLine()){
String s = sc.nextLine().replaceAll("\s+", "");
if(s.length()>14){
System.out.printf("%s %s %s
", s.substring(0, 6), s.substring(6, 14), s.substring(14, s.length()));
}else if(s.length()>6){
System.out.printf("%s %s
", s.substring(0, 6), s.substring(6, s.length()));
}else{
System.out.println(s);
}
}
}
}
