Question

I have started learning scala and I wonder is there a way I could get elements in the List from the right side

For example

val myList = List(1, 2, 3, 4, 5)

if I writemyList(-1) I would get 5.

Is there any simple way to get it done or I’ll have to write my own function?

Answer 1

myList.last

? Remember that this operation has O(n) complexity for List. Also you can simply reverse the list and use normal indices:

myList.reverse(0)
