The easiest way to do this is by using the tail
and zip
:
val xs = Seq('A', 'B', 'C', 'D', 'E')
xs zip xs.tail
If efficiency is a concern (i.e. you don't want to create an extra intermediate sequence by calling tail
and the Seq
you use are not List
s, meaning that tail
takes O(n)) then you can use views:
xs zip xs.view.tail
