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: Accepted)

#include<stdio.h>
int main()
{
	int a,b,c;
	char s[11];
	scanf("%s",&s[0]);
	a=1000*(s[0]-48)+100*(s[1]-48)+10*(s[2]-48)+s[3]-48;
	b=10*(s[5]-48)+s[6]-48;
	c=10*(s[8]-48)+s[9]-48;
	if(a<2020&&b<5&&c<31){
		printf("Heisei");
	}else{
		printf("TBD");
	}
}
