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;
#define int long long
#define mod 1000000007



signed main(){
    string s;
    cin >> s;

    int y = 0;

    for(int i = 0;i<=3;i++){
        y = pow(10,3-i)*(s[i]-'0');
    }
    int m = 0;
    for(int i = 5;i<7;i++){
        m += pow(10,1+5-i)*(s[i]-'0');
        //cout << m << endl;
    }
    int d = 0;
    for(int i = 8;i<10;i++){
        d += pow(10,8+1-i)*(s[i]-'0');
    }
    //cout << m << " " << d << endl;

    if((m<4 || (m==4 && d<=30)))cout << "Heisei" << endl;
    else cout << "TBD" << endl;
    return 0;
