You don't need it. Think about it, you can just use a stack (or a recursive function.)

Which of the following traversal is used for printing the keys of binary search tree in ascending order?

In order traversal is used.


Is sorting a binary search tree simple?

A binary search tree is already ordered. An in order traversal will give you a sorted list of nodes.


What is the purpose of performing a binary search tree inorder traversal?

Performing a binary search tree inorder traversal helps to visit all nodes in the tree in ascending order, making it easier to search for specific values or perform operations like sorting and printing the elements in a sorted order.


How can you merge two binary search trees into a single binary search tree?

To merge two binary search trees into a single binary search tree, you can perform an in-order traversal on each tree to extract their elements, combine the elements into a single sorted list, and then construct a new binary search tree from the sorted list. This process ensures that the resulting tree maintains the binary search tree property.


C program which accepts in order and preorder traversal outputs of a binary tree as input and prints the corresponding binary tree?

any body can help on this ?


What is the significance of the reverse postorder traversal in binary trees?

Reverse postorder traversal in binary trees is significant because it allows for efficient processing of nodes in a specific order: right child, left child, root. This traversal method is useful for tasks like deleting nodes or evaluating expressions in a tree structure.


What is the process for conducting a reverse in-order traversal of a binary tree?

To conduct a reverse in-order traversal of a binary tree, start at the right child, then visit the root node, and finally visit the left child. Repeat this process recursively for each node in the tree until all nodes have been visited.


What assumption about the list is made when binary search is conducted?

Binary search requires that the list be in search key order.


Definition of threaded binary tree?

A binary tree variant that allows fast traversal: given a pointer to a node in a threaded tree, it is possible to cheaply find its in-order successor (and/or predecessor).


Items that are not suitable for a binary search?

The only items suitable for a binary search are those which are in a sorted order.


Algorithm to determine if a binary tree is complete binary?

There are many ways of checking for a complete binary tree. Here is one method:1. Do a level order traversal of the tree and store the data in an array2. If you encounter a nullnode, store a special flag value.3. Keep track of the last non-null node data stored in the array - lastvalue4. Now after the level order traversal, traverse this array up to the index lastvalue and check whether the flag value is encountered. If yes, then it is not a complete binary tree, otherwise it is a complete binary tree.


What is traverse technique used in chain survey?

1. pre-order b-tree traversal. 2. in-order b-tree traversal. 3. post-order b-tree traversal
