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: Accepted)

#include <stdio.h>

char S[15];
char S2[15]="2019/04/30";

int main(){

scanf("%s",S);

int i;

for(i=0;i<10;i++){
if(i==4||i==7){continue;}
if(S[i]-'0'>S2[i]-'0'){printf("TBD\n");return 0;}
else if(S[i]-'0'<S2[i]-'0'){printf("Heisei\n");return 0;}
}

printf("Heisei\n");

return 0;
}
