Kotlin Immutable Random
import kotlin.random.Random
/**
* Denotes an instance of [Random] that does not mutate its own internal state. Unlike standard [Random],
* [ImmutableRandom] will always return the same value for subsequent calls to [nextBits], [nextInt], etc. One must
* call [nextRandom] to get a new instance of [ImmutableRandom] with a state that would typically have been updated
* internally.
*
* For the same seed, any sequence of `next*(), nextRandom()` should yield the same result as a normal [Random] calling
