You don't need it. Think about it, you can just use a stack (or a recursive function.)
In order traversal is used.
A binary search tree is already ordered. An in order traversal will give you a sorted list of nodes.
Binary search requires that the list be in search key order.
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.

In order traversal is used.
A binary search tree is already ordered. An in order traversal will give you a sorted list of nodes.
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.
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.
any body can help on this ?
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.
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.
Binary search requires that the list be in search key order.
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).
The only items suitable for a binary search are those which are in a sorted order.
