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: Accepted)

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

int main()
{
    string s; cin>>s;
    string y="";
    string m="";
    string d="";
    for(int i=0;i<4;i++) y+=s[i];
    for(int i=5;i<7;i++) m+=s[i];
    for(int i=8;i<10;i++) d+=s[i];
    int yi=stoi(y);
    int mi=stoi(m);
    int di=stoi(d);
    if(yi>2019)cout<<"TBD"<<endl;
    else if(yi<2019)cout<<"Heisei"<<endl;
    else{
        if(mi<=4)cout<<"Heisei"<<endl;
        else if(mi>4)cout<<"TBD"<<endl;
    }
    return 0;
