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

Solution in C (GCC 5.4.1) (judge verdict: Accepted)

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

int main(){
    char S[32], tmp[32];
    int seireki;
    scanf("%s", S);
    
    int j=0;
    for (int i=0; S[i] != '\0'; i++) {
        if (S[i] != '/') {
            tmp[j] = S[i];
            j++;
        }
    }
    seireki = atoi(tmp);
    if (seireki < 20190431) {
        printf("Heisei");
    }else{
        printf("TBD");
    }
    return 0;
