Generate a sequence of Fibonacci number in Scala [duplicate]

Answer 1

There are many ways to define the Fibonacci sequence, but my favorite is this one:

val fibs:Stream[Int] = 0 #:: 1 #:: (fibs zip fibs.tail).map{ t => t._1 + t._2 }

This creates a stream that is evaluated lazily when you want a specific Fibonacci number.

EDIT: First, as Luigi Plinge pointed out, the "lazy" at the beginning was unnecessary. Second, go look at his answer, he pretty much did the same thing only more elegantly.
