Answer 1

Answer:

Kindly find the code snippet in the explanation written in kotlin language

Explanation:

fun main(args: Array<String>) {

   var num:Int

   println("Enter a num")

    num= Integer.valueOf(readLine())

   for(i in num downTo 1){

       if(i==num){

           print("Ready!")

           print(" ")

       }

       print(i)

       print(" ")

       if(i==1){

           print(" ")

           print("Go!")

       }

   }

}

This function too can also work

fun numTo(num:Int){

   if (num>0) for(i in num downTo 1) print("$i ")

   println("Go!")
