is there a good equivalent of a "multiset" in Kotlin? I don't care about order. I simply care about element count and I want to compare equality between to multisets.

[Andrew Gazelka]

i.e., [1,4,4,7] == [7,4,1,4]

[Tsvetozar Bonev]

You could easily implement this with a extension function

[Shawn]

I don’t believe this is available in the stdlib

[Andrew Gazelka]

alright, I'll just implement my own then

[Andrew Gazelka]

wait... I could probably just compare groupings

[Alan Evans]

What language does multiset come from? How does it differ from a set?

setOf(1, 4, 4, 7) == setOf(7, 4, 1, 4)

[Shawn]

@Alan Evans I’ve seen it in C++, Google provides it for the JVM with Guava

[Shawn]

it differs by allowing multiple instances of the same element

[Alan Evans]

right, so multiSetOf(1, 4, 4, 7) != multiSetOf(7, 4, 1, 1) ?

[Shawn]

right
