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

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

package main

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

func main() {
	var s string
	fmt.Scanln(&s)

	fmt.Println(logic(s))
}

func logic(s string) string {
	a := strings.Replace(s, "/", "", -1)
	b, _ := strconv.Atoi(a)

	if b < 20190501 {
		return "Heisei"
	}
	return "TBD"
}
