sorted

sorted returns a list of collection elements sorted according to their natural sort order (ascending).

sortedBy sorts elements according to natural sort order of the values returned by specified selector function.

import kotlin.math.abs

fun main() {

    val shuffled = listOf(5, 4, 2, 1, 3, -10)                   // 1
    val natural = shuffled.sorted()                             // 2
    val inverted = shuffled.sortedBy { -it }                    // 3
    val descending = shuffled.sortedDescending()                // 4
    val descendingBy = shuffled.sortedByDescending { abs(it)  } // 5

    println("Shuffled: $shuffled")
    println("Natural order: $natural")
    println("Inverted natural order: $inverted")
    println("Inverted natural order value: $descending")
    println("Inverted natural order of absolute values: $descendingBy")
}

1. Defines a collection of shuffled numbers.
2. Sorts it in the natural order.
3. Sorts it in the inverted natural order by using -it as a selector function.
4. Sorts it in the inverted natural order by using sortedDescending.
5. Sorts it in the inverted natural order of items' absolute values by using abs(it) as a selector function.
