Once again the REPL shows how this works: scala> val b = 0 +: a b: Vector [ Int] = Vector ( 0, 1, 2, 3 ) scala> val b = Vector ( -1, 0) ++: a b: Vector [ Int] = Vector ( -1, 0, 1, 2, 3 ) Because Vector is not a linked-list (like List ), you can prepend and append elements to it, and the speed of both approaches should be similar.

Looking at Scala collections from a high level, there are three main categories to choose from: 1. Sequences are a sequential collection of elements and may be indexed (like an array) or linear(like a linked list) 2. Maps contain a collection of key/value pairs, like a Java Map, Python dictionary, or Ruby Hash 3. Set… Näytä lisää
