Correct Answer: Dn = log 2 (n+1)
Explanation:
A complete binary tree is a binary tree where all the levels have maximum number of nodes except possibly the last level.
The depth of complete binary tree of n nodes will be Dn=log 2 (n+1) where Dn is the height or depth of the tree and n is the number of nodes.
Correct Answer: Yes---a primitive data type is used to store characters
