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: Wrong Answer)

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

int main(void){
    int Y=0, M=0;
    char S[15];
    scanf("%s", S);
    Y += 1000*(S[0]-'0');
    Y += 100*(S[1]-'0');
    Y += 10*(S[2]-'0');
    Y += S[3]-'0';
    M += 10*(S[5]-'0');
    M += S[6]-'0';
    printf("%d %d\n", Y, M);
    if(Y>2019) printf("TBD\n");
    else if(Y==2019){
        if(M>4) printf("TBD\n");
        else printf("Heisei\n");
    }
    else printf("Heisei\n");
    return 0;
}
