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

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

#include <stdio.h>
int main(void)
{
    char a[100];
    for(int i = 0; i< 100;i++)
    {
        a[i] = 0;
    }
    gets(a);
    if(a[5] != '0' || a[6] > '4')
    {
        puts("TBD");
    }
    else
    {
        puts("Heisei");
    }
    return 0;
}
