Create a binary linked tree, and traverse the tree by using the recursive function. The structure of the tree is as follows: //check pic// You should input the nodes in pre-order sequence. If a child of a node is NULL, input a space. Write the function of create binary tree, pre-order to print the nodes, in-order to print the nodes and post-order to print the nodes. Count the height of the tree. Hints: Header file typedef char ElemType; typedef struct node//define the type of binary tree node { }BTnode; Source file #include <stdio.h> #include <stdlib.h> #include "tree.h" BTnode * createTree()//create the binary tree，return the root { BTnode *tnode;// tnode is the root char elem; ;//input the character //if the input is a space，set the pointer as NULL Else// if the input is not a space，generate the binary node and create its left…

Recall that the set of full binary trees is defined as follows:
Consider the following binary tree: (this is NOT a binary search tree) root 6 8 9 15 10 16 11 12 17 13 14 18 19 23 20 21 22 24 25 Suppose we implement contains(x) using the basic recursive traversal approach as a starting point. A private recursive helper method would look like static boolean helper (target, node) if node is null then return false if node.value== target then return true findLeft := helper (target, node.left) findRight := helper (target, node.right) return findLeft OR findRight If we call helper(3, root) (using the tree above), how many times is helper called in total (including this first call)?

Could you use the traditional way of removing a value from a binary search tree and apply it to a treap? Show how. › Re-implement the Remove method without recursion. › * Given a treap of height h, provide an example that requires 2h rotations to bring the root of the treap to a leaf position? please give explanation to this questions with also time complexity and implement it in c#
How to answer the following question screenshot shows our binary search tree For the binary search trees, the public method, size, calls the private recursive method, recSize, and passes it a reference to the root of the tree, returning to the caller whatever is returned to it by recSize. Critique the following implementation of recSize assuming its parameter variable is node: if (node == null) return 0; else if ((node.getLeft() == null) && (node.getRight() == null)) return 1; else if ((node.getLeft() == null)) return (1 + recSize(node.getRight())); else return (1 + recSize(node.getLeft())); A. The code will throw a "null pointer exception" under certain circumstances. B. The code will return an incorrect result under certain circumstances. C. The code works correctly but could be simpler. D. The code works correctly. If an application uses the remove method on an Iterator object returned by our binary search tree: A. a TreeUnderflowException is…
Can help in Java? Qustion : Using Binary search tree write a Java program to Insert and print the element in (in-Order traversal ), then search the elements (a and z) in the tree… provided that user enters the values.
: You are implementing a binary search tree class from scratch, which, in additionto insert, find, and delete, has a method getRandomNode() which returns a random nodefrom the tree. All nodes should be equally likely to be chosen. Design and implement an algorithmfor getRandomNode, and explain how you would implement the rest of the methods.
java binary tree: Given the following binary search tree, what would be the sequence of nodes, if traversed using inorder traversal after deleting 8.
