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[10];
    int y, m, d, ymd;

    scanf("%s", s);

    ymd = (s[0] - '0') * 10000000;
    ymd += (s[1] - '0') * 1000000;
    ymd += (s[2] - '0') * 100000;
    ymd += (s[3] - '0') * 10000;
    ymd += (s[5] - '0') * 1000;
    ymd += (s[6] - '0') * 100;
    ymd += (s[8] - '0') * 10;
    ymd += (s[9] - '0');

    d = ymd % 100;
    ymd /= 100;
    m = ymd % 100;
    ymd /= 100;
    y = ymd;

    if(y <= 2019 && m <= 4 && d <= 30){
        printf("Heisei\n");
    }
    else{
        printf("TBD\n");
    }

    return 0;
