You may collaborate on this homework with AT MOST one person, an optional "homework buddy".

MAY ONLY BE TURNED IN ON GRADESCOPE BEFORE THE DUE DATE,
There is NO MAKEUP for missed assignments;
in place of that, we drop the lowest scores (if you have zeros, those are the lowest scores.)

Reading: Recursive Algorithms Review, DS 9.1, PS 14.1 and 14.2

(10 pts) Fill in the information in the header. The following are required to get the 10 "participation" points.
- Filling in your name and umail address.
List two important pieces of information stored in an activation record (as discussed on p. 442 in the DS textbook):
1. (5 pts) 1.
2. (5 pts) 2.
There are two important parts to every simple recursive function: the base case, and the recursive call that makes progress towards the base case. (There are other forms of recursion, such as "mutual recursion", where foo() calls bar() and bar() calls foo(), but let's set those aside for the moment, and deal only with simple recursive functions). Something that can go wrong with recursion when it is used incorrectly is a stack overflow. Explain two different ways that a recursive function could be writen incorrectly that could lead to stack overflow. Hint: one has something to do with the base case, and the other has to do with the recursive call.
1. (5 pts) 1.
2. (5 pts) 2.

Given a fairly common definition for a struct Node that can be used to make a singly linked list of int values:
```
struct Node {
  int data;
  Node *next;
}
```
1. (10 pts) Write an iterative function printList(Node* head) that takes a pointer to the head Node of the singly linked list and prints each value of the linked list, one per line. Write the entire function (including the function signature), and be sure to write correct and compilable C++ code in your solution.
2. (10 pts) Rewrite the printList(Node* head) function from part a. recursively.
