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 date[10];
    int c[10],year,month,day,i;

    for(i=0;i<10;i++){
        c[i] = getchar();
    }

    year = (c[0]-'0')*1000 + (c[1]-'0')*100 + (c[2]-'0')*10 + (c[3]-'0');
    month = (c[5]-'0')*10 + (c[6]-'0');
    day = (c[8]-'0')*10 + (c[9]-'0');

    int sum;
    sum = year*10000 + month*100 + day;

    if(sum <= 20190430){
        printf("Heisei\n");
    }else{
        printf("TBD\n");
    }

    return 0;
