Problem Statement

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.

Input

Input is given from Standard Input in the following format:

S

Output

Print Heisei if the date represented by S is not later than April 30, 2019, and print TBD otherwise.

Sample Input 1

2019/04/30

Sample Output 1

Heisei

Sample Input 2

2019/11/01

Sample Output 2

TBD

Solution in C++14 (GCC 5.4.1) (judge verdict: Accepted)

#include<bits/stdc++.h>
using namespace std;
int main(){
  string s;
  cin>>s;
  int y=1000*(int)(s.at(0)-'0')+100*(int)(s.at(1)-'0')+10*(int)(s.at(2)-'0')+(int)(s.at(3)-'0');
  int m=10*(int)(s.at(5)-'0')+(int)(s.at(6)-'0');
  int d=10*(int)(s.at(8)-'0')+(int)(s.at(9)-'0');
  cout<<(y<=2019&&(y<2019||m<=4)&&(m<4||d<=30)?"Heisei":"TBD")<<endl;
}
