Solution in Kotlin (1.0.0) (judge verdict: Accepted)

import java.io.PrintWriter

val pw = PrintWriter(System.out)

fun main(args : Array<String>) {
    func()
    pw.flush()
}

fun func() {
    val s = next()
    println(if (s.substring(5, 7).toInt() < 5) "Heisei" else "TBD")
}

fun next() = readLine()!!

fun println(value : Any) {
    pw.println(value)
}
