Scala: Project Euler problem 2

by Gregor Uhlenheuer on July 17, 2012

There you go, the second problem of Project Euler:

Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be:

1, 2, 3, 5, 8, 13, 21, 34, 55, 89, …

By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms.

This solution uses a lazily evaluated sequence (Stream) where each element is computed as it is requested.
