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

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

#include <stdio.h>


int main(void)
{
	char s[10];
	
	scanf("%s",s);
	
	int year = 1000*s[0]+100*s[1]+10*s[2]+s[3];
	
	int month = 10*s[5]+s[6];
	
	if(year < 2019){
		puts("Heisei");
	}else if(year == 2019 && month <= 4){
		puts("Heisei");
	}else if(year == 2019 && month >= 5){
		puts("TBD");
	}else{
		puts("TBD");
	}
	
	return 0;
