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.

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

var lines =[];


var readline = require("readline");
var rl = readline.createInterface({
  input:  process.stdin,
  output: process.stdout
});

rl.on('line',function(x){
  lines.push(x);
});

rl.on('close',function(){

  var date = lines[0].split("/");
  var year = Number(date[0]);
  var month= Number(date[1]);
  var day= Number(date[2]);

  if(year<2019){console.log("heisei");}
  else{
    if(date[1]<5){
    console.log("heisei");
    }
    else{
    console.log("TBD");
    }
  }

  
});
