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>

int main() {
    char ymd[10];
    scanf("%s", ymd);
    int iymd;
    int i;
    char cymd[8];
    for(i=0; i<4; i++) {
        cymd[i] = ymd[i];
    }
    for(i=5; i<7; i++) {
        cymd[i-1] = ymd[i];
    }
    for(i=8; i<10; i++) {
        cymd[i-2] = ymd[i];
    }
    iymd = atoi(cymd);

    if(iymd <= 20190430) {
        printf("%s\n", "Heisei");
    } else {
        printf("%s\n", "TBD");
    }
    return 0;
}
