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

S

Output

Print Heisei if the date represented by S is not later than April 30, 2019, and print TBD otherwise.

Solution in JavaScript (node.js v5.12) (judge verdict: Accepted)

var stdin = require("fs").readFileSync("/dev/stdin", "utf8");
stdin = stdin.trim().split("\n").reverse();
function input(){return stdin.pop()}
var stdout = [];


s = input().split("/")
if (parseInt(s[1], 10) < 5){
    stdout.push("Heisei")
}else{
    stdout.push("TBD")
}


stdout = stdout.join(" ");
console.log(stdout);
