Which node contains a pointer to its parent?a) root nodeb) right most childc) left most childd) left sibling
Which of the following statements are correct for the expression trees? (Select all that applies.) a. An expression tree is a binary tree. b. The root and internal nodes are operators. c. Each leaf is an operand. d. Subtrees are sub-expressions, with the root being an operator. 2. The height of a binary tree is the maximum number of edges in any root to leaf path. The maximum number of nodes in a binary tree of height h is: a. (2^h)-1 b. (2^(h+1))-1 c. 2*(h+1)-1 3. Which of the following statements are correct? (Select all that applies.) a. The maximum number of internal and external nodes in a proper binary tree with n nodes are (n-1)/2 and (n+1)/2, respectively. b. The maximum number of nodes at level k (k = 0,1,2,...) of a proper binary tree: 2^k c. Depth of a node refers to the number of ancestors. d. Height of a tree refers to the the maximum of the depths of its leaf positions.
Which of the following statements are correct for a binary search tree?a) The root always contains the largest key.b) All keys in the left subtree are always smaller than any key in the corresponding right subtree. 4 c) All leaves are located on the same level. d) Each subtree is also a binary search tree.
C PROGRAMMING •Write a program that counts how many lotto tickets each person has bought .•Create a sorted binary tree .•In the tree node you have to store first name, last name, number of tickets and references to two nodes. •Read the file lotto300k.txt into a binary tree. •Traverse the completed tree and print those customers that bought more than one ticket.

The value of the third smallest elementis ”3”. You may choose either a recursive or an iterative solution. Youare NOT allowed to actively maintain an extra data-structure for storageof values of the tree elements to perform a linear scan later to return therequired value.HINT: A certain BST Traversal is ordered.
void doo(node<int>*root){ if(root !=0) { node<int>*p=root; while(root->next!=0) root=root->next; p->data=root->data; } What is this code do? a. swap the first item with the last item in the linked list b. doesn't do anything because the root parameter is passed by value c. set the first item in the linked list as the last item d. change the root item in the binary tree with the farthest leaf item
hi can you please explain to me this code. it is Tree traversal inorder. how are these written // Inorder traversal void inorderTraversal(struct node* root) { if (root == NULL) return; inorderTraversal(root->left); printf("%d ->", root->item); inorderTraversal(root->right);
Hi, I had a question about Python. I am programming a binary search tree. You can use Java or C++ if someone does not now Python. The problem is that I am having troubling printing out the binary search tree diagram. Here is my code below: class BSTNode:def __init__(node, value):node.value = valuenode.leftChild = Nonenode.rightChild = None# Insertion code# No duplicates.# Start of of the insert definitiondef insert(node, value):if node == node.value:returnelif value < node.value:elif node.rightChild:node.rightChild.insert(value)else:node.rightChild = BSTNode(value)else:if node.leftChild:node.leftChild.insert(value)else:node.leftChild = BSTNode(value)node_elements = [100, 66, 120, 76, 34, 27, 90, 45, 76, 89, 15, 7,15, 60, 43, 99,27, 16, 13, 150]root = BSTNode(node_elements[0])for i in range(1, len(node_elements)):root.insert(node_elements[i]) Questions: What code is needed to print the binary search tree module?
