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 Go (1.6) (judge verdict: Accepted)

package main

import (
	"fmt"
	"strconv"
	"strings"
)

func main() {
	// 勉強用。先人の丸パクリです
	var s string
	fmt.Scan(&s)
	//スラッシュでsplitさせてAtoi
	ss := strings.Split(s, "/")
	a ,_ := strconv.Atoi(ss[0])
	b ,_ := strconv.Atoi(ss[1])
	c ,_ := strconv.Atoi(ss[2])
	if a <= 2019 && b <= 4 && c <= 30 {
		fmt.Println("Heisei")
		return
	}
	fmt.Println("TBD")
  //ひどいなこれは
