Reversal of a Set can be done using reversed() method. It is independent of the alphabets. And is not a sort. It is just a reversal.
fun main() {
var x = mutableSetOf("Mohan", "Kriti", "Salim")
var y = x.reversed()
println("The Set in reversed order is "+y)
}
So, in the above code we have created a Set and initialised to the variable x.
var x = mutableSetOf("Mohan", "Kriti", "Salim")Below is how the values are positioned in the Set,

Then we have used the reversed() Function to reverse the elements of the Set x.
var y = x.reversed()
And the Set x gets sorted in reverse order with Salim as the first value, Mohan second and Kriti as the third.

And we get the below output.
The Set in reversed order is [Salim, Kriti, Mohan]
