Answer 1

Hi! you don't have a valid input check for a given range, and what should your program output if the data is out of bounds? read the task carefully again

Answer 2

#try this:
fun main(args: Array<String>) {
val names = arrayOf("Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday")
var day = readLine()!!.toInt()
if(day <= 6 && day >= 0) {
println(names[day]) }
else {
println("Invalid day")
}
}

Answer 3

fun main() {
println("Enter a number of days: ")
val day = readln().toInt()
val days = arrayOf("Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday")
if (day <days.size)
println(days[day])
else println("Index out of bound")
}
