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

#include<iostream>
#include<string>
using namespace std;

int main(){
  string S;
  cin >> S;
  
  string year, month, day;
  string y0{S[0]};
  string y1{S[1]};
  string y2{S[2]};
  string y3{S[3]};
  string m0{S[5]};
  string m1{S[6]};
  string d0{S[8]};
  string d1{S[9]};
  
  year = y0+y1+y2+y3; 
  month = m0+m1; 
  day = d0+d1; 
  
  if(year < "2019"){
    cout << "Heisei" << endl;
  }
  
  else if(year > "2019"){
    cout << "TBD"<<endl;
  }
  else if(year == "2019" && month > "04"){
    cout << "TBD" << endl;
  }

else{
cout << "Heisei" << endl;
}
  
  return 0;
