How do I find the min() or max() of two Option[Int]

Question

How would you find minValue below? I have my own solution but want to see how others would do it.

val i1: Option[Int] = ...
val i2: Option[Int] = ...
val defaultValue: Int = ...
val minValue = ?

Answer 1

I think this is what you're after:

val minValue = List(i1, i2).flatten match {
  case Nil => defaultValue
  case xs => xs.min
}

I'd avoid sorted since sorting requires a lot more processing than simply finding the max or min (although it probably doesn't make much difference in this case).
