READ THE PROBLEM AND USE PYTHON PROGRAMMING LANGUAGE!!In 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…
Rewrite the definition of the function searchNode of the class B-tree provided (bTree.h) by using a binary search. Write a C++ code to ask the user to enter a list of positive integers ending with -999, build a b- tree of order 5 using the positive integers, and display the tree contents. Also, ask the user to enter a number to search and display if the number is found in the tree. bTree.h

Write a program in c++ to do the following operations on a Binary Search Tree (BST) considering the inputs are a set of strings that represent the names of 12 months of a year (in the order of January, February, . . ., December). i) Print the successor and predecessor of any given node. ii) Search a particular string is present in the BST or not. iii) Delete any string from the BST.
2. You have a family tree diagram like the following, very smallI, sample tree and file. It is stored as a file with the following format (parent: , one line for all people in the tree). Your task is to be able to find the descendants of any person in a family tree, e.g. the descendants of p1 are p4.p5,p7,p8 in O(|P|) time, where P is the set of people in the graph. "Sketching" the approach is fine but you may give full pseudocode, just reuse an algorithm from class, perform some obvious conversion (Adjacency Matrix to/from Array List, etc.) or some combination of these. You may not use depth first search or breadth first search. You may preprocess the input with any polynomial approach and may assume the |P| people in the tree are labelled po, p1, .p. p0: p4, p5 p1: p4, p5 p2: p6 p3: p6 p4: p4 p5: p7, p8 p6: p7, p8 p7: p8: p7 p8 Preprocess File By: How to retrieve descendants (O(|P|) time, max): getDescendants(Person ):
