Consider the following binary search tree (BST) with the node (#70) circled in red.

You are going to simulate the operation of an AVL tree on paper. For the purposes of this assignment, assume that new returns addresses in the following order: @1480 @1120 @1096 @1264 @1180 @1192 @1768 @1804 @1228 @1372 @1312 @1276 @1168 @1696 @1084 @1504 @1468 @1216 @1384 @1204 @1648 @1024 @1108 @1396 @1144 @1432 @1252 @1348 @1564 @1072 @1684 @1540 @1672 @1624 @1420 @1588 @1300 @1792 @1060 @1720 @1336 @1612 @1552 @1324 @1636 @1660 @1288 @1708 @1732 @1492 @1780 @1528 @1156 @1444 @1036 @1456 @1240 @1576 @1516 @1756 @1360 @1132 @1408 @1600 @1744 @1048 Also note that if you remove all references to an address (so it is garbage collected), it goes to the back of the queue (so would be after whatever is the last address in the AVL at that time). For delete() of a node with two children, I want you to assume that we replace the data (but not the node itself) with the successor value (and that the successor is removed and garbage collected). There are no duplicates allowed, so if there's a…
Provide the frequency and the Huffman encoding for each character in the following string: better late than never Provide the frequency and encoding for each character in the string. Insert the letters and their frequencies into the priority queue in the alphabetic order below, with blank first. When a node with the same frequency is inserted in the priority queue, it is placed after other nodes with the same frequency already in the priority queue. Refer to algorithm 3.4.1. Encode the resulting graph with the left child as O and the right child as 1.
Your system consists of nodes connected in a full binary search tree of height 6. If a node has failed, it is unreachable, as are all of its descendants, as shown in the figure below (the node with the red star has failed). You randomly select a node from the tree, and want to traverse from the root of the tree to your selected node. You are unaware that one node (you don't know which one) has failed, potentially causing your traversal to fail, depending on which node you're looking for and which node failed. All nodes are equally likely to fail. Assuming that exactly one node has failed, which of the following statements is true? Pick ONE option The likelihood of success is between 90-100% The likelihood of success is between 80-89.99%. The likelihood of success is between 70-79.99%. The likelihood of success is between 60-69.99%. The likelihood of success is between 50-59.99%.
Given a binary search tree and data of two nodes, find 'LCA' (Lowest Common Ancestor) of the given two nodes in the BST.LCALCA of two nodes A and B is the lowest or deepest node which has both A and B as its descendants. Example:In this example, the green coloured node is the LCA to A and B.Alt TextNote:It is defined that each node is a descendant to itself, so, if there are two nodes X and Y and X has a direct connection from Y, then Y is the lowest common ancestor.Example:Alt TextNote:1. If out of 2 nodes only one node is present, return that node. 2. If both are not present, return -1.3. all the node data will be unique.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 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…
Create a programme that accepts the integer N from the command line, creates a random BST of size N, then iterates the loop N times by deleting a random key (using the code delete(select(StdRandom.uniform(N))) and inserting a random key. After the loop, calculate and report the internal path length multiplied by N plus one to get the average length of a path in the tree. Run your programme for N = 102, 103, and 10 4 to test the seemingly paradoxical claim that this approach lengthens the tree's average route in a proportionate manner to N's square root. the identical tests should be performed for a delete() implementation that randomly selects whether to utilise use the predecessor or the successor node
Given a binary tree T and a source node s in it, provide the pseudocode for an iterative algorithm to traverse T starting from s using breadth-first traversal, also known as level-order traversal. Each node in T contains an integer key that can be accessed. Each time a node is visited, its key should be printed. Note: You do not have to implement your algorithm.
Describe a method for finding the middle node of a doubly linked list with header and trailer sentinels by “link hopping,” and without relying on explicit knowledge of the size of the list. In the case of an even number of nodes, report the node slightly left of center as the “middle.” What is the running time of this method? Hint: Consider a combined search from both ends. Also, recall that a link hop is an assign- ment of the form ”p = p.getNext( );” or ”p = p.getPrev( );”.
