readLine for a variable number of Ints

Is there a way to code something like this in kotlin for a variable number of ints? For example the input should be "1 3 5" or "3 2 2 7" (String with space-separated Ints). And I am not allowed to use java librarys. 

val (x, y) = readLine()!!.split(' ').map(String::toInt)
println(x+y)

Thanks in advance.

If you want to just print each string, then you can use forEach

readLine()!!.split(' ').forEach{ println(it) }

If you want to print as int, then you can use forEach with toInt()

readLine()!!.split(' ').forEach{ println(it.toInt()) }

Or if you want sum you can use sumBy directly 

readLine()!!.split(' ').sumBy{ it.toInt() }

Found a solution for my problem:

var list: List<Int> = readLine()!!.split(' ').map(String::toInt)
for(m in  list){
    println(m)
}
