import kotlin.test.*

fun main(args: Array<String>) {
//sampleStart
val list = listOf("aa", "b", "bb", "a")

val lengthThenString = compareBy<String> { it.length }.thenBy { it }

val sorted = list.sortedWith(lengthThenString)
println(sorted) // [a, b, aa, bb]

val sortedReversed = list.sortedWith(lengthThenString.reversed())
println(sortedReversed) // [bb, aa, b, a]
//sampleEnd
