Test your knowledge

This is an ungraded check of your knowledge (i.e. I do not look at these results in any way shape or form--nor do they effect your grade).

They are designed so you can have some feedback on the assigned readings/videos/notes to see if you picked up some of the basic knowledge.

A node in a tree can have any number of nodes. That might be 1 node (A linked list is a very special type of tree), 2 nodes (in the case of a binary tree), or a more generic tree may have 3 or more nodes.
