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.

Sample Input 2

2019/11/01

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

const input = require('fs').readFileSync('/dev/stdin', 'utf8');

const nenn = Number(input.split('').slice(0, 4).join(''));

const month = Number(input.split('').slice(5, 7).join(''));

const hi = Number(input.split('').slice(8, 10).join(''));

if (nenn < 2019) {
  console.log('Heisei');
} else if(month < 5) {
  console.log('Heisei');
} else {
  console.log('TBD');
}
