What is the maximum number of nodes at level 'l' in a binary tree?
l
l^2
2l
2^l
If a perfect binary tree has a height of 'h', how many nodes are present in the tree?

2^h - 1
2^(h+1) - 1
2h
What is the primary advantage of using an iterative approach (with a stack) over recursion for Inorder Traversal?
Iterative traversal is generally faster.
Iterative traversal is easier to understand and implement.
There is no significant advantage; both approaches have similar performance.
Iterative traversal avoids function call overhead and potential stack overflow for very deep trees.
Which data structure is used in the iterative implementation of Preorder Traversal?
Linked List
Queue
Heap
Stack
The diameter of a binary tree is defined as:
The longest path between any two nodes in the tree.
The height of the tree.
The shortest path between the root and any leaf node.
The number of nodes in the tree.
Which data structure is most suitable for implementing Level Order Traversal efficiently?
Binary Heap
Which of the following is a common application of Binary Tree serialization?
Finding the shortest path in a graph
Storing and retrieving trees in a file or database

What is the advantage of using a level order serialization for a Binary Tree?
Reduced space complexity
More efficient for finding the LCA
Preserves the level order traversal of the tree
Easier to implement than other serialization methods
