Binary Tree Traversal

What is the order of nodes visited in an Inorder traversal of a binary tree?

• Root, Left, Right

• Left, Root, Right

• Right, Left, Root

• Left, Right, Root

In a Preorder traversal, which node is visited first?

• Left Child

• Right Child

• Root Node

• Leaf Node

During a Postorder traversal, which of the following sequences is correct?

• Root, Left, Right

• Left, Right, Root

• Right, Root, Left

• Left, Root, Right

Which of the following is a common application of binary trees?

• Storing data in a linear array

• Implementing priority queues

• Managing user sessions in web applications

• Performing arithmetic operations

If a binary tree is traversed in Inorder, what will be the output if the tree contains the values 1, 2, and 3?

• 3, 2, 1

• 1, 2, 3

• 2, 1, 3

• 1, 3, 2

How would you apply Postorder traversal to delete a binary tree?

• Visit the root first, then delete

• Delete the left subtree, then the right subtree, and finally the root

• Delete the right subtree, then the left subtree, and finally the root

• Delete the root first, then the subtrees

Which traversal method would you use to evaluate an expression tree?

• Inorder

• Preorder

• Postorder

• Level Order

What is the main difference between Preorder and Inorder traversal?

• The order of visiting nodes

• The type of tree structure

• The number of nodes visited

• The method of storing nodes

Evaluate the effectiveness of using binary trees for hierarchical data representation.

• They are inefficient for large datasets

• They provide a clear structure for parent-child relationships

• They are only useful for small datasets

• They complicate data retrieval processes

Which of the following statements best describes a binary tree?

• A tree where each node has at most two children

• A tree where each node can have any number of children

• A linear structure of nodes

• A structure that only allows leaf nodes
