Expert Solution & Answer
Chapter 21, Problem 8MC
Program Description Answer
Each level in the complete binary tree except the last level must have 2l nodes where “l” is the level. The depth of the complete binary tree satisfies the condition “d<= log n + 1” where, “n” is the number of nodes. Each and every node in a complete binary tree which a right child, also has a left child.
Hence, the correct answer is option “D”.

Suppose that in a binary tree (not binary search tree), if the value of a node is greater
than at least one of its children, then it is considered a "power node. For example, in
the following tree, nodes 25 is a power node because is greater than both children
16 and 9. Similarly, node 16 is also a power node as it is greater than the left child
12. Other power nodes include 24 and 17. Consequently, in this tree, there are four
power nodes.

Complete the non-recursive method count PowerNodes, which takes a TreeNode
parameter node (a reference to a node in a binary tree) and retums the number of
power nodes in the tree rooted at node. If node is null or there are no power
nodes, the method returns 0.
