牛客网编程练习之去哪儿网2017校招题：身份证分组

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\n", s.substring(0, 6), s.substring(6, 14), s.substring(14, s.length()));
}else if(s.length()>6){
System.out.printf("%s %s\n", s.substring(0, 6), s.substring(6, s.length()));
}else{
System.out.println(s);
}
}

}

}
