Question

Can anyone explain how to reverse a Scala list with a example?

Answer 1

Hi,

This reverses the order of elements in a list using the List. reverse method.

Here is an example you can follow:

scala> a

res6: List[Int] = List(1, 2, 3)

scala> a.reverse

res7: List[Int] = List(3, 2, 1)

scala> a

res8: List[Int] = List(1, 2, 3)
