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:

Solution in C (GCC 5.4.1) (judge verdict: Wrong Answer)

#include<stdio.h>
char str[10];
int i;
int main(void){
    for(i = 0;i < 10;i++){
        scanf("%s",&str[i]);
    }
    if(str[6] == '1'||'0'||'2'){
        if(str[5] == '1'){
            printf("TBD");
        }
    else
    if(str[6] == '4'||'3'||'2'||'1'){
        printf("heisei");
    }else{
        printf("TBD");
    }}
    return 0;
}
