import java.util.Random

fun main(args: Array<String>) {

   val answers = listOf(
       "It is certain", "It is decidedly so", "Without a doubt",
       "Yes, definitely", "You may rely on it", "As I see it, yes",
       "Most likely", "Outlook good", "Signs point to yes", "Yes",
       "Reply hazy, try again", "Ask again later",
       "Better not tell you now", "Cannot predict now",
