Question

Remember, in our definition, the height of a binary tree means maximum number of nodes from the root to a leaf.

 

 

 

a) In a perfect binary tree of size n, what is the tree's exact height?  Justify your answer.

 

 

 

b) In a degenerate binary tree of size n, what is the tree's exact height?  Justify your answer. 

 

 

 

c) What is the maximum height for a balanced binary tree of size 7? Justify your answer

 

 

Expert Solution
Step 1

Here is your solution:

 

a). Perfect binary tree:

A binary tree in which every node has exactly two child nodes and all the leaf node are at the same level.

A perfect binary tree of height h, has (2h+1 - 1) node

So, A perfect binary tree with n nodes has height, log(n+1) -1
