#include<bits/stdc++.h>
using namespace std;
int main(){
  int y,m,d;
  char a,b;
  cin>>y>>a>>m>>b>>d;
  if(m>=5){
    cout<<"TBD";
  }
  else{
    cout<<"Heisei";
  }
}
### Prompt

Your challenge is to write a CPP solution to the following problem:

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.

Examples

Input

2019/04/30


Output

Heisei


Input

2019/11/01


Output

TBD

### Response

```cpp
#include<bits/stdc++.h>
using namespace std;
int main(){
  int y,m,d;
  char a,b;
  cin>>y>>a>>m>>b>>d;
  if(m>=5){
    cout<<"TBD";
  }
  else{
    cout<<"Heisei";
  }
}
```
