Kotlin - Get maximum value with its key in a set

Issue

I have a defined a set like below.

val resultSet: Set<Pair<Driver,Int>>

How to get maximum value of above resultSet set with its key?

Solution

You can use the maxBy function. It returns the maximum value given by the extractor you pass to it, or null if the set is empty. You could do something like this:

val maxPair = resultSet.maxBy { it.second }
