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<iostream>
using namespace std;

int main(){
  char a[10];
  for(int i=0; i<10; ++i){
    cin>>a[i];
    a[i]=a[i]-'0';
  }
  bool can=true;
  if(a[0]*1000+a[1]*100+a[2]*10+a[3]>=2020) can=false;
  else if((a[0]*1000+a[1]*100+a[2]*10+a[3]==2019)&&(a[5]*10+a[6]>=5)) can=false;
  else if((a[0]*1000+a[1]*100+a[2]*10+a[3]==2019)&&(a[5]*10+a[6]==4)&&(a[8]*10+a[9]>=30)) can=false;
    
  if(can) cout<<"heisei"<<endl;
  else cout<<"TBD"<<endl;
