1. Mark which topics are covered in the chapter that you were supposed to read for this week:
2. For a simple class Node
public class Node{
public int info;
public Node link;
}
that describes a linked list of integers, write a method
for computing the sum of all the integers from this list.
For extra credit: write a recursive method for
performing this search; main idea: compute the sum of the tail and
add the first element.
