- = Suppose that we have a B and the size of the search key field V is equal to 10 bytes, the size of the data (record) pointer Pr 6 bytes, and the tree (block) pointer P is 5 bytes and the value of p (the order or the maximum number of a tree pointers in a node) is equal to 20 for an internal node. a) Calculate the block size (B) b) Suppose that we have a B- tree instead of B and based on the block size found in question (a), calculate the order (p) for an internal node in this case.COMPLETE THE GIVEN CODE BELOW TO SOLVE THE PROBLEM - PYTHONIn this problem, you are going to implement a filesystem using a tree data structure. Similar to a filesystem, each node (or file), may have multiple children. If the specified path does not exist, then you should disregard that file. Once you are done adding elements to the filesystem, you should print the directory structure in the specified format. Required modifications: 1. Insertion of a new element 2. Printing of the directory from the root node. 3. Parsing of the input. Input Format First line is the name of the root directory. Second line, n, is the number of subdirectories that follows. For each line that follows, it shows the following format: Filename-root node,next path,next path,... Constraints You may assume that the filenames are all alphabetical characters with no special characters. n < 100 The maximum path length is 20 (including the root directory). You may assume that there are no similar…Create a binary linked tree, and traverse the tree by using the recursive function. The structure of the tree is as follow: 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.

- In C++, develop an algorithm that inserts the value val into a binary search tree with root. If the tree is empty, root = null. The algorithm returns the root of the tree containing the added item. You should assume that “new node” creates a new node with data field data and reference fields left (for left child) and right (for right child).In a database file structure, the search key field is 14 bytes long, the block size is 512 bytes, a record pointer is 8 bytes and a block pointer is 7 bytes. The largest possible order of a non-leaf node if B+ tree implements this file structure isIn C++ Construct a binary search tree, in order from the intergers given in the input argument vector. Assume there are no duplicates given. Assume the tree is order as follows: left child is smaller then parent , right child is larger then the parent. Insert nodes in the order provided do not balance or reorder. Inputs: {1,2,3,4},4,2 CODE: int BSTdistance (std::vector<int> values, int nodeA, int nodeB) { }

Each element of the array must keep track of the array locations of the left child and the right child as well as a reference to the data element that is placed there. In order to reuse such slots, you must also keep track of the accessible array positions where items have been deleted.
- IN C LANGUAGE When inserting a node into a linked list, where (in memory) will that node be placed if there is no overflow? A) The location of the AVAIL pointer B) The next contiguous spot of memory from the last node C) The very end of the contiguous memory block D) A randomized memory locationCreate an array version of a binary search tree based on an array implementation of a binary tree using the simulated link approach. Each array element must maintain a reference to the data element that was placed there, as well as the array positions of the left and right children. You must also preserve a record of accessible array places where items have been erased so that those slots may be reused.BST - Binary Search Tree - implement a BSTNode ADT with a data attribute and two pointer attributes, one for the left child and the other for the right child.
