If you have a function that generates the next state based on the previous one, you can then use the iterate function to create the entire list. In this case, the state consists of the four numbers and the size. After calling iterate, I call map fst to get rid of the size values, and concat to concatenate all the lists.
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.
