Ranges in Kotlin

How do I write code to return a range of 10 numbers from a given number.

i.e if I am given 5, code should return 0..9

358 should return 350..359

33 should return 30..39 etc

You can use the following code:

fun answer(givenNum: Int) : IntRange {
    val startOfRange = givenNum - (givenNum % 10)
    return startOfRange until (startOfRange + 10)
}

fun main() {
    val givenNum = 33
    println(answer(givenNum)) // 30..39
}

If the given number is integer type, you can simply write

val x = 358
(x / 10 * 10)..(x / 10 * 10 + 9)

Do you mean something like this?

fun range10(contained: Int): IntRange {
    val start = contained - contained % 10
    val end = start + 9
    return start..end
}
