Practice: Recursive toString

Take out a piece of paper. We’ll be programming on paper.

• Implement a recursive toString() method for a LinkedList.

public class LinkedList<E> {
  private LinkedNode<E> head;
  int size;

  public String toString() {
   // your code
  }
}

• Use a recursive helper method.

• What is the base case?

• How do we make the problem smaller?
