kotlin sortedby descending

The sortedByDescending function is used to sort elements in a collection in descending order based on the result of the given selector function. It returns a new list of elements sorted in the specified order.

Here's an example:

data class Person(val name: String, val age: Int)

fun main() {
    val people = listOf(Person("Alice", 29), Person("Bob", 31), Person("Charlie", 25))
    val sortedPeople = people.sortedByDescending { it.age }
    println(sortedPeople)
}

In this example, we have a list of Person objects. We use the sortedByDescending function with a selector function { it.age } to sort the list of people in descending order based on their age. The resulting sortedPeople list will contain the Person objects sorted by age in descending order.
