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.

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

let main = (standardInput) => {
  let date = standardInput.split('/').join('')
  if (Number(date) >= 2019430) console.log('TBD')
  else console.log('Heisei')
}

main(require('fs').readFileSync('/dev/stdin', 'UTF-8'))
