The file canalso contain the keyword delete followed by a number. Search for a node within the tree for thatnumber and delete it. If the number is not found, insert the node. The tree will not contain anyduplicates.Sample input.txt file1238568delete 3delete 9Note:delete 88The above lines will not be in the file because delete 8 will insert a new node since it doesn't exist andthen, the 8 on the next line will attempt to insert a second 8, which would be a duplicate.At the end, display the tree in preorder, inorder, and postOrder format. Also, display the tree level bylevel (breadth search format). The display should be redirected to a file (output.txt).Note: When deleting, make sure to account for no children, one child and two children.

In the attached file, you will find a function that creates a binary search tree of a given size and files that will randomly generate keys in the range [1,1000]. The value associated with each key can be passed to the function, default is 1. Complete the program by implementing the necessary code to perform the following tasks: Create a binary search tree of size 20, name it bst Print all keys in bst on a single line to save space Print the mimimum key in bst Print the smallest key larger than 500 in bst (if any) Print all keys in the range [100,300] in bst Print the tree height Import the modules first before doing this. from bst.binary_search_tree import TreeMapfrom AVLTreeMap import AVLTreeMapimport random def create(size, value = 1): bst = AVLTreeMap() # or just use AVLTreeMap() counter = 0 while counter<size: val = random.randint(1,1000) if not val in bst.keys(): bst[val] = value counter +=1 return bst
The program, word_frequency, counts the number of occurrences of words in a document. The program takes a filename as a parameter and performs the task. Get the program to run using the attached text file called document.txt. The file contains a piece of text. After you run the program and understand it's logic, modify word_frequency.py to use a binary search tree instead of a dictionary. Tasks: 1. Import a binary search tree 2. Change the filename in the program to reflect the change(s) made Python Only and no other coding languages. Import the module first before running it. Please show output when done. (build off of this file and try not to change too much) word_frequency.py: import sysfilename = sys.argv[1] freq = {}for piece in open(filename).read().lower().split():# only consider alphabetic characters within this pieceword = ''.join(c for c in piece if c.isalpha())if word: # require at least one alphabetic character freq[word] = 1 +…
Create some code to see how well the Java HuffmanTree class performs. The programme will have to parse a text and generate a frequency table of characters from that document. Once the table is constructed, a Huffman code tree is made, and the file's code is represented by a string of '0' and '1' characters. Then, using that string as a template, re-generate the original file's contents, and print them.
Computer Science You want to save a binary search tree into a file. which traversal you will use so that you can restore the original binary search tree? Group of answer choices Preorder Inorder Postorder
Write an application to test the HuffmanTree class. Your application will need to read a text fileand build a frequency table for the characters occurring in that file. Once that table is built, createa Huffman code tree and then a string consisting of '0' and '1' digit characters that represents the code string for that file. Read that string back in and re‐create the contents of the original file
Create a Huffman code tree and a string of '0' and '1' characters to represent that file's code string after building that table. Read that string again and print the actual file's contents.
The programming language is Python Instructions: Create a function that will delete a node in a Linked List based on position number. On below example, if you want to delete position #2, it will remove the Banana (arrangement of nodes below is Apple, Banana, Cherry, Grapes, Orange). myLinkedList = LinkedList() myLinkedList.append("Banana") myLinkedList.append("Cherry") myLinkedList.append("Grapes") myLinkedList.append("Orange") myLinkedList.prepend("Apple") myLinkedList.deleteByPositionNum(2) node = myLinkedList.head while node: print(node.value, " ") node = node.next_node You may start with the function head:def deleteByPositionNum(self, positionNum):
Write a Java program that creates and maintains a binary search tree (BST) whose nodes are studentrecords. Each student record (BST node) contains the student’s id (String), name (String) and GPA(float). Use the student id as a key for the BST. The program starts with an empty BST and offers thefollowing menu options to the user repeatedly until the user selects the ‘Q’ option (quit). A: Add a new student record to the BST.Here the user is prompted to enter the new student’s id, name and GPA. The program shoulddisplay an error message if the student id already exists in the BST. F: Find a student record. Here the user is prompted to enter the id of the student to be searched. If found the programdisplays the student id, name and GPA, otherwise the program displays an error message. D: Delete a student record. Here the user is prompted to enter the id of the student record to be deleted. The program shoulddisplay an error message if the student id is not found in the BST.

With a given binary search tree, you are asked to save the key of all the nodes into a file, then read the values one by one sequentially from the saved file and build a binary search tree that exactly replicates the original binary search tree. Describe how you would do it and give an example of 5 nodes.
When is a graph a tree? Write a program that will read from a file specified on the command line and determine from the graph's adjacency matrix whether or not it is a tree. Example: Ja.out graph.txt Output: The graph is a tree! Contents of graph.txt will be something like this: 5 01000 10111 01000 01000 01000
