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:

Solution in C (GCC 5.4.1) (judge verdict: Wrong Answer)

#include<stdio.h>
int main(void)
{
  char x, y, z, n;
  char a, b;
  scanf("%4d %c %1d %1d %c %2d", &x, &a, &y, &n, &b, &z);
  if(x<2019){
    printf("Heisei");
  }else if(x==2019|y==0|n<=4){
  printf("Heisei");
}else{
  printf("TBD");
  }
  return 0;
}
