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

#include <bits/stdc++.h>
using namespace std;
signed main(){
  char a[100];
  cin>>a;
  if(a[5]=='0'){
    if(a[6]<='3')
      cout<<"Heisei"<<endl;
    else if(a[6]=='4'){
      if(a[8]=='3' && a[9]=='0'){
    cout<<"Heisei"<<endl;
      }

      else if(a[5]<='2'){
      cout<<"Heisei"<<endl;
      }
    }
    else
      cout<<"TBD"<<endl;
  }
  else
    cout<<"TBD"<<endl;
  return(0);
}
