Replace an element at an index in a list in Erlang?

I wouldn't recommend using a list in this way, it makes me think that your problem might be design related rather than related to solving it neatly. Perhaps if you explains what you have the list for?

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.
