Assume that the nodes of a binary tree are all unique and that you are provided the order of elements encountered in a preorder traversal and the order of elements encountered in a postorder traversal. Under what situations can you properly recreate the tree structure using these two traversal orders?
Suppose the nodes of a binary tree are unique and that you are given the order of elements as they are encountered in a preorder traversal and the order of the elements as they are encountered in a postorder traversal. Under what conditions can you accurately reconstruct the structure of the tree from these two traversal orders?
Write a technique that quickly determines if any two nodes u and v in a tree T whose root node is s are descendants or ancestors.

- Given that a tree with a single node has a height of one, what is the maximum number of nodes that may be included in a balanced binary tree with a height of five?arrow_forwardIterativeThe iterative method for visiting the nodes in the infix series should be written using traversal(tree). As previously mentioned, it is overly complex and is only included to demonstrate what you should avoid. This is a binary tree. As is usual, each node has a value and pointers to the sources of its left and right subtrees. Furthermore, each component is linked to its progenitor.post-cond: Searches the tree for infixes.arrow_forwardWrite a technique that quickly identifies whether u is a descendant or ancestor of v in a tree T whose root node is s.arrow_forward

Create a binary tree for which two given lists of n labels 0, 1,..., n - 1 are formed through the tree's inorder and postorder traversals. Additionally, your method should identify inputs for which there is no solution to the issue.arrow_forward
- Some implementations of a binary tree do not use null to indicate the absence of a child. Instead, they use references to a single dummy node. A reference to an empty tree is to this same dummy node. Modify the implementation of BinaryTree in this way.

- Assume that each node in a binary tree is distinct and that you are provided both the order in which items are discovered during a preorder traversal and a postorder traversal. How correctly can you deduce the structure of the tree from these two traversal orders, and under what circumstances?arrow_forwardSuppose that in a binary tree (not binary search tree), if the value of a node is greater than at least one of its children, then it is considered a "power node. For example, in the following tree, nodes 25 is a power node because is greater than both children 16 and 9. Similarly, node 16 is also a power node as it is greater than the left child 12. Other power nodes include 24 and 17. Consequently, in this tree, there are four power nodes. 25 16 IN 12 24 17 28 16 23 31 10 Complete the non-recursive method count PowerNodes, which takes a TreeNode parameter node (a reference to a node in a binary tree) and retums the number of power nodes in the tree rooted at node.
