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 day[100];
    scanf("%s", day);
    int y = 0, m = 0, d = 0;
    int ok = 1;
    for (int i = 0; i < 4; i++) y = y * 10 + (day[i] - '0');
    for (int i = 5; i < 7; i++) m = m * 10 + (day[i] - '0');
    for (int i = 8; i < 10; i++) d = d * 10 + (day[i] - '0');
    if (y != 2019) ok &= (y < 2019);
    else {
        if (m != 4) ok &= (m < 4);
        else if (d != 30) ok &= (d < 30);
    }

    printf("%s\n", (ok ? "Heisei" : "TBD"));
}
