Q:

Of the following tree structure, which is, efficient considering space and time complexities?

A) Incomplete Binary Tree B) Complete Binary Tree
C) Full Binary Tree D) None
 
Answer & Explanation Answer: B) Complete Binary Tree

So complete binary tree is the better one since the property of complete binary tree is maintained even after operations like additions and deletions are done on it.
