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

import java.util.*
//import kotlin.math.*
 
private fun readString() = readLine()!! // string line
private fun readInt() = readString().toInt() // single int
private fun readLong() = readString().toLong()
private fun readStrings() = readString().split(" ") // list of strings
private fun readInts() = readStrings().map { it.toInt() } // list of ints
private fun readLongs() = readStrings().map { it.toLong() } // list of ints
 
val INF = 1000000000
 
fun main(args: Array<String>)
{
    var a = readInt()
	print(a*a*a)
}
