Hmm...wondering why nobody's posting any questions for this assignments. Neway, I was just wondering if neone know how to do or even start #2, becuz it just got confusing by adding doubly linked list...?  |

i just started with the base case with 1 node which has 0 non-null pointers.

I did it the same way as Yingster.

Here's a tip: Note that when you add a node that there are 2 more non-null pointers that are created.

the formula doesn't work for n = 0, so base case must be n = 1

does the base case really work for n = 1? when it does, it means that there's no null pointers, but that can't be...
what if the main pointer of the single node is not a null pointer... that would make it at least one null pointer...
it would make sense if the base case was 2

no, we're looking at non-null pointers, not nullls

that's what i mean... given ONE node, you'll have 3 pointers in it... would you? the prev, the main and the next... or is it just a node with just a prev and a next and nothing else?

With one node you'll have ZERO non-null pointers. The pointer to the next link will be null and the pointer to the previous node will be null (since there's only one node in the list). Therefore there are ZERO non-null pointers.
