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: Wrong Answer)

#include<bits/stdc++.h>
using namespace std;
int main(){
  string S,Y,M,D;
  cin>>S;
  for(int i=0;i<4;i++){
    Y=Y+S.at(i);
  }
  for(int i=5;i<7;i++){
    M=M+S.at(i);
  }
  for(int i=8;i<10;i++){
    D=D+S.at(i);
  }
  int y=stoi(Y);
  int m=stoi(M);
  int d=stoi(D);
  bool flag=true;
  if(y>=2020){
    flag=false;
  }
  else if(y==2019&&m>=5){
    flag=false;
  }
  if(flag==true){
    cout<<"TBD"<<endl;
  }
  else{
    cout<<"Heisei"<<endl;
  }
