import java.util.HashMap;
import java.util.Scanner;
public class FirstCharacterWithNFrequency {
        public static void main(String[]args) {
                Scanner sc = new Scanner(System.in);
                String str = sc.next();
                HashMap<Character, Integer> hm = new HashMap<Character, Integer>();
                for(int i=0;i<str.length();i++) {
                        if(hm.containsKey(str.charAt(i))) {
                                int currfreq = Integer.parseInt(hm.get(str.charAt(i)).toString());
                                hm.put(str.charAt(i), currfreq + 1);
                        } else {
                                hm.put(str.charAt(i), 1);
                        }
                        int freq = Integer.parseInt(hm.get(str.charAt(i)).toString());
                        if(freq == 3) {
                                System.out.print("First Character encountered with frequency three is: " + str.charAt(i));
                                break;
                        }
                }
        }
