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

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

#include <stdio.h>
int main(){
  int a,b,c,d,e,f,g,h;
char s[15];
scanf ("%s",s);
a=s[0]-'0';
b=s[1]-'0';
c=s[2]-'0';
 d=s[3]-'0';
 e=s[5]-'0';
 f=s[6]-'0';
 g=s[8]-'0';
 h=s[9]-'0';
if ((a*10000000)+(b*1000000)+(c*100000)+(d*10000)+(e*1000)+(f*100)+(g*10)+h < 20190431){
printf ("Heisei");
}
  else {
  printf ("TBD");
  }
return 0;
