FWIW, slice takes one bite out of the array whereas values_at can remove several bites. I mention this because it isn't clear if your application ultimately needs to remove or otherwise process the last element in the c array. You may well be facing a further step in dealing with the last item.

values_at can take an argument list of and arbitrary number of indices OR ranges.

>a = %w{ a b c d e f }
=> ["a", "b", "c", "d", "e", "f"]

> a.values_at(2..-1)
=> ["c", "d", "e", "f"]

> a.values_at(2..-2)
=> ["c", "d", "e"]

> a.values_at(2,-2)
=> ["c", "e"]
