Scala: read and save all elements of an Iterable?

This is easy. A few thousand elements is nothing, so it hardly matters unless it's a really tight loop. So the flippant answer is: use whatever you feel is most elegant.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
