Challenge: Tavern.kt Part 2

Kotlin Programming: The Big Nerd Ranch Guide 19. Functional Programming Basics

Here is my solution:

val patronGold: MutableMap<String, Double> = uniquePatrons.map {
    it to 10.0
}.toMap() as MutableMap<String, Double>

What do you think, guys? Are there any easier or more concise ways of solving it?

edit: never mind, I just learned about distinct() from another thread

What was your solution to part 1 of the challenge? I can’t seem to make it work in true functional style… :thinking:

Another way:
val patronGold = uniquePatrons.associateWith { 6.0 }
