    class Solution{

    public static void main(String[] args){
    Scanner in = new Scanner(System.in);
    while(in.hasNext()){
        String IP = in.next();
        System.out.println(IP.matches(new MyRegex().pattern));
    }
}

    }

    `class MyRegex { String pattern = "^(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\." + "(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\." + "(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\." + "(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)$"; }
