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

Solution in Go (1.6) (judge verdict: Accepted)

package main
 
import (
	"bufio"
    "time"
    "fmt"
    "os"
 )

var sc = bufio.NewScanner(os.Stdin)

func main() {
    var str string
    if sc.Scan() {
        str = sc.Text()
    }
  
  layout := "2006/01/02"
  s, _ := time.Parse(layout, str)
  
  tbd := "2019/05/01"
  t, _ := time.Parse(layout, tbd)
  
  if s.Unix() < t.Unix() {
    fmt.Println("Heisei")
  } else {
    fmt.Println("TBD")
  }
}
