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

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

#include<bits/stdc++.h>
using namespace std;

int main(void)
{
  string s;
  cin>>s;

  int year=(int)s[3];
  int month1=(int)s[5];
  int month2=(int)s[6];
  int day=(int)s[9];
  if(year<=9&&month1=='0'&&month2<='4'&&day<='3')
    cout<<"Heisei"<<endl;
  else
    cout<<"TBD"<<endl;
  
}
