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

int main (void) {
    char s[11] = {'\0'};
    char *year, *month;
    char **endptr = NULL;
    scanf("%s", s);

    year = strtok(s, "/");
    long year_l = strtol(year, endptr, 10);
    month = strtok(NULL, "/");
    long month_l = strtol(month, endptr, 10);

    if ( year_l < 2019 ) {
        printf("Heisei\n");
    }
    else if ( year_l == 2019 ) {
        if ( month_l <= 4 ) {
            printf("Heisei\n");
        }
        else {
            printf("TBD\n");
        }
    }
    else {
        printf("TBD\n");
    }
    return 0;
}
