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

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

typedef long long ll;

template<typename T>
void out(T x) { cout << x << endl; exit(0); }
#define watch(x) cout << (#x) << " is " << (x) << endl

const int maxn = 1e6 + 5;
int get(string s, int i, int j) {
  int res = 0;
  for (int k=i; k<j; k++) {
    res=res*10;
    res += (s[k]-'0');
  }
  return res;
}

int main() {
  ios_base::sync_with_stdio(false); cin.tie(0);  cout.tie(0);
  cout << fixed << setprecision(12);
  //2019/04/30
  string s; cin>>s;
  int year = get(s,0,4);
  if (year>2019) out("TBD");
  if (year<2019) out("Heisei");
  int month = get(s,5,7);
  if (month>4) out("TBD");
  if (month<4) out("Heisei");
  int day = get(s,8,10);
  if (day<=30) out("Heisei");
  out("TBD");

  

  return 0;
