Threaded Binary Tree

How are Threads typically implemented?

• Using a separate thread array

• By overloading pointer fields with flags

• Storing thread IDs in nodes

• Via external hash table

The inorder predecessor of a node in a right threaded binary tree can be found by:

• following the left thread

• Traversing the left subtree

• following the right thread

• checking the parent pointer

Which traversal in a threaded binary tree does NOT require a stack or recursion?

• Level-Order Traversal

• Preorder Traversal

• Inorder Traversal

• Postorder Traversal

In a threaded binary tree , a thread is a:

• Pointer to the root node

• Pointer to the child node

• Pointer to the ancestor node

• Pointer to the inorder successor/predecessor

What is the advantage of a threaded binary tree over a standard binary tree?

• Faster insertion and deletion

• No need for extra memory fro stack/recursion in traversal

• Better balancing of tree

• Reduced height of the tree

Which type of treaded binary tree contains thread only for NULL right pointer?

• Fullu Threaded

• Single Threaded(Left)

• Double Threaded

• Single Threaded(Right)

In a double threaded binary tree, threads are used to point to

• Only left children

• Only right children

• Both inorder successor and predecessor

• Parent nodes

What is the primary purpose of using threads in a threaded binary tree?

• To simplify the insertion process

• To increase the height of the tree

• To facilitate faster traversal

• To reduce the number of nodes

In a single threaded binary tree, which pointer is typically used for threading?

• Left child pointer

• Both child pointers

• Right child pointer

• Parent pointer

Which traversal method can be performed without using additional memory in a threaded binary tree?

• Inorder Traversal

• Postorder Traversal

• Preorder Traversal

• Level-Order Traversal
