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 (GCC 5.4.1) (judge verdict: Wrong Answer)

#include <stdio.h>
#include <stdlib.h>

int main(void)
{
  char S[100], ANS[100], yyyymmdd[9];
  
  scanf("%s", S);
  yyyymmdd[0]=S[0];
  yyyymmdd[1]=S[1];
  yyyymmdd[2]=S[2];
  yyyymmdd[3]=S[3];
  yyyymmdd[4]=S[5];
  yyyymmdd[5]=S[6];
  yyyymmdd[6]=S[8];
  yyyymmdd[7]=S[9];
  yyyymmdd[8]=0x00;

  if (atoi(yyyymmdd)<=20190430) {
    printf("Heisei\n");
  } else  {
    printf("TDB\n");
  }
  
  return 0;
}
