I guess I am rolling - here goes problem number 6:
class Euler006 extends Euler {
def number = 6
def solution = {
def sumOfSquares(n : Int) = {
Stream.range(1, n+1, 1).map(x => x * x).sum
}
def squareOfSums(n : Int) = {
val sums = Stream.range(1, n+1, 1).sum
sums * sums
}
squareOfSums(100) - sumOfSquares(100)
}
}This one contains nothing too special at all. In fact I am not too sure if there is any real benefit in using Stream.range instead of Range.
