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

S

Output

Print Heisei if the date represented by S is not later than April 30, 2019, and print TBD otherwise.

Sample Input 1

Sample Input 2

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

#include<stdio.h>

int main(){
  int y, m, d;
  scanf("%d/%d/%d", &y, &m, &d);

  if(y < 2019 || (y == 2019 && m < 4) || (y == 2019 && m == 4 && d <= 30)){
    printf("Heisei\n");
  }
  else printf("TBD\n");

  return 0;
