### Prompt

Your task is to create 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<iostream>
using namespace std;
int main()
{
int a,b,c;
char x,y;
cin>>a>>x>>b>>y>>c;
if(b>4)
{
	cout<<"TBD"<<endl;
}
else
{
	cout<<"Heisei"<<endl;
}
}
```
