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>
int main(){
    char s[11];
    int f=0;
    scanf("%s",s);
    if(s[0]>'2') f=1;
    else if(s[0]=='2'&&s[1]>'0') f=1;
    else if(s[0]=='2'&&s[1]=='0'&&s[2]>'1') f=1;
    else if(s[0]=='2'&&s[1]=='0'&&s[2]=='1'&&s[3]>'9') f=1;
    else if(s[0]=='2'&&s[1]=='0'&&s[2]=='1'&&s[3]=='9'&&s[5]>'0') f=1;
    else if(s[0]=='2'&&s[1]=='0'&&s[2]=='1'&&s[3]=='9'&&s[5]=='0'&&s[6]>'4') f=1;

    if(f==1)
        printf("TBD");
    else
        printf("Heisei");

    return 0;
