1.Suppose that we first insert an element x into a binary search tree that does not already contain x. Suppose that we then immediately delete x from the tree. Will the new tree be identical to the original one? If yes, please justify your answers with no more that 3 sentences. If no, please give a counterexample. You may draw pictures if need 2. Draw pictures to show how to construct a red-black tree by inserting the keys in the following sequence into an initially empty red-black tree: 8, 4,10, 9, 5, 17. Show each steps. Please use a double edge indicates a red pointer and single edge indicates a black pointer.

This exercise is about drawing BSTs. You are asked to: Show the result of inserting 3, 1, 4, 6, 9, 2, 5, and 7 in an initially empty binary search tree. Then show the result of deleting the root. Draw all binary search trees that can result from inserting permutations of 1, 2 and 3. How many types of trees are there? What are the probabilities of each type of tree’s occurring if all permutations are equally likely Given the input {4371, 1323, 6173, 4199, 4344, 9679, 1989}, a fixed table size of 10, and a hash function H(X) = X mod 10, show the resulting Linear probing hash table Separate chaining hash table

Suppose a BST contains the integer values 1 through 15 and is a perfect binary tree. a) Draw the tree. b) Suppose we call the removeViaReplace method, with r equal to the root of the tree in Part a. List the numbers in child->value at the beginning of each iteration of the while loop in the code below. After that, redraw the tree upon completion of the removeViaReplace function. c) Repeat Part b, but use the tree obtained at the end of Part b as the initial tree this time. static void removeViaReplace(Node* r) { Node* temp = r->right; if (temp->left == nullptr) { r->value = temp->value; r->right = temp->right; delete temp; } else { Node* child = temp->left, * parent = temp; while (child->left != nullptr) { parent = child; child = child->left; } r->value = child->value; parent->left =…

For questions 4 – 6, indicate for each of the following statements if it is true or false and explain why.4. The subtree of the root of a red-black tree is always itself a red-black tree.5. The sibling of a null child reference in a red-black tree is either another null child reference or ared node.6. The worst case time complexity of the insert operation into an AVL tree is O(log n), where n isthe number of nodes in the tree.
Given a set of 10 letters { I, D, S, A, E, T, C, G, M, W }, answer the following: a) With the given letters above, we can construct a binary search tree (based on alphabetical ordering) and the sequence < C, D, A, G, M, I, W, T, S, E > is obtained by post-order traversing this tree. Construct and draw such a tree. NO steps of construction required.b) The letter S is first removed from the binary search tree determined above, followed by inserting a new letter R. Draw the updated binary search tree after removal and insertion. Choose the logical predecessor (not successor) of the removing node if necessary c) Determine and list the sequence of elements obtained by pre-order traversing the updated binary search tree after removal and insertion above.

Given a binary tree and an integer S, print all the pair of nodes whose sum equals S.Note:1. Assume the given binary tree contains all unique elements.2. In a pair, print the smaller element first. Order of different pairs doesn't matter.Input format :The first line of input contains data of the nodes of the tree in level order form. The data of the nodes of the tree is separated by space. If any node does not have a left or right child, take -1 in its place. Since -1 is used as an indication whether the left or right nodes exist, therefore, it will not be a part of the data of any node.The following line of input contains an integer, that denotes the value of S.Output Format :Print each pair in a new line, as described in the task.
