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>
#include<string.h>
#include<stdlib.h>

int main(void){
    char str[10];
    for(int i=0;i<10;i++)scanf("%c", &str[i]);
    char *ptr;

    int a = strtol(strtok(str,"/"),NULL,10);
    int b = strtol(strtok(NULL,"/"),NULL,10);
    int c = strtol(strtok(NULL,"/"),NULL,10);
    if(a < 2019){
        printf("Heisei");
    }else if(a == 2019){
        if(b < 4){
            printf("Heisei");
        }else if(b == 4){
            if(c <= 30){
                printf("Heisei");
            }else{
                printf("TBD");
            }
        }else{
            printf("TBD");
        }
    }else{
        printf("TBD");
