You are given a string S as input. This represents a valid date in the year 2019 in the yyyy/mm/dd format. (For example, April 30, 2019 is represented as 2019/04/30.)

Write a program that prints Heisei if the date represented by S is not later than April 30, 2019, and prints TBD otherwise.

Constraints

S is a string that represents a valid date in the year 2019 in the yyyy/mm/dd format.

Solution in Java8 (OpenJDK 1.8.0) (judge verdict: Accepted)

import java.util.*;

class Main{
  public static void main(String args[]){
    Scanner sc = new Scanner(System.in);
    String s = sc.next();
    int y = Integer.valueOf(s.substring(0,4));
    int m = Integer.valueOf(s.substring(5,7));
    int d = Integer.valueOf(s.substring(8));
    if(y<=2019){
      if(m<=4){
        if(d<=30){
          System.out.println("Heisei");
          return;
        }
      }
    }
    System.out.println("TBD");
  }
}
