Since the Math.min() function only allows for the use of 2 elements, I was wondering if there is maybe another function which can calculate the minimum of more than 2 elements.
Thanks in advance!
If you have multiple elements you can just chain calls to the min method:
Math.min(x, Math.min(y, z))
Since scala adds the a min
method to numbers via implicits you could write the following which looks much fancier:
x min y min z
If you have a list of values and want to find their minimum:
val someNumbers: List[Int] = ???
val minimum = someNumbers.min
Note that this throws an exception if the list is empty. From scala 2.13.x onwards, there will be a minOption method to handle such cases gracefully. For older versions you could use the reduceOption
method as workaround:
someNumbers.reduceOption(_ min _)
someNumbers.reduceOption(Math.min)
Add all numbers in the collection like the list and find a minimum of it.
scala> val list = List(2,3,7,1,9,4,5)
list: List[Int] = List(2, 3, 7, 1, 9, 4, 5)
scala> list.min
res0: Int = 1
