To analyze the search path in this ordered binary search tree for the target value 296, I will evaluate how the search process proceeds at each visited node and how the BST property guides the next step. Option 1: 300 as the first examined item. When searching for 296 in a BST, you start at the root. The root of this tree is 300. Since 296 is less than 300, you move to the left child of 300. Therefore, it is correct that 300 is examined first. Option 2: 192 as the second examined item. After comparing 296 with the root 300 and observing that 296 ......Login to view full explanation

BST_Srch3 Below is a BST  When searching for Node 78 which node is visited 4th? Note that this is a BST not an AVL tree. AVL balancing is not a concern.

CC7_03 Create a function that takes in a Binary Search Tree (BST) and a positive integer k, returning the kth largest integer value within the BST. Assume that the BST only contains integer values and that k will always be less than or equal to the total number of nodes in the tree. For this question, duplicate integers are treated as distinct entries. For instance, in a BST with values {5, 7, 7}, the second largest value would be 7—not 5. Each BST node has an integer value, a left child node, and a right child node. A node is a valid BST node only if it adheres to the BST properties: its value is strictly greater than all values of nodes in its left subtree, and less than or equal to all values of nodes in its right subtree. The children nodes are either valid BST nodes themselves or None / null. Sample input: Sample output: 17 Given the following implementation to traverse_reverse_in_order(node, k, tree_data), which test case would fail? It is guaranteed that all the other methods are correctly implemented. The input trees depicted in the DcStrings of test cases are guaranteed to be accurate.

BST6, BST_Srch11 Based on our Binary Search Tree search method discussions in our lectures. Below is an algorithm written for BST search. This is not an AVL Tree so balancing is not a concern. What would be the run time complexity on average of this search algorithm  written for a BST ? BSTSearch(tree, key) { cur = tree⇢root while (cur is not null) { if (key == cur⇢key) { return cur // Found } else if (key < cur⇢key) { cur = cur⇢left } else { cur = cur⇢right } } return null // Not found }
