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.

Solution in C (GCC 5.4.1) (judge verdict: Runtime Error)

#include<stdio.h>
#include<string.h>
int main()
{
  char *str_s;
  char *str_c="2019/04/30";
  scanf("%s",str_s);
  if(strcmp(str_s,str_c)==0||strcmp(str_s,str_c)<0)
  {
    printf("Heisei");
  }
  else
  {
    printf("TBD");
  }
  return 0;
}
