    The process felt very manageable, and the staff guided me through each step. With Invisalign Newnan, I noticed gradual improvements in my teeth alignment without any discomfort. Scheduling appointments was simple, and following the treatment plan became easy and stress-free. Overall, it made staying consistent with the aligners much more straightforward.

    //Write your code here class MyRegex{ public String pattern;

    public MyRegex() {
    this.pattern = "^(\\d{1,2}\\.|[01]\\d{2}\\.|2[0-4]\\d\\.|25[0-5]\\.){3}(\\d{1,2}|[01]\\d{2}|2[0-4]\\d|25[0-5])$";
}

    }
