python 8.7 LAB: Writing append and search methods (singly-linked list)Given main.py and a Node class in Node.py, complete the LinkedList class in LinkedList.py by writing the append() and search() methods. The search() method should return the Node whose data value matches a given key, and None if the key is not found. The search() method should also set the position of each Node searched in the LinkedList, starting with 1. Ex: If the input is: 12 23 59 37 923 212the output is: 12 found in list at position 1.If the input is: 12 23 59 37 923 268the output is: 68 not found in list.
I need answer question pls Project Operations Write a JAVA program that will maintain a phone directory using a Linked-List. The program should be able to perform the following operations: 1) Add persons details (first name, last name, phone number, city, address, sex and email) to the phone directory, where phone numbers in the directory have to be unique. (Note: each person record will store in one node in the linked-list and insert each person to the last) 2) Delete any person details by a given phone number. 3) Update telephone number by providing person first name. 4) Display all details of persons from a phone directory. 5) Search telephone number based on person first name. (Note: use sequential search to find all telephones for the given first name) 6) Sort all persons in the phone directory ascending based on person first name. (Note: use bubble or selection sort to arrange the entire phone directory) Project Outputs The output has to display a menu of choices. Then the…

2.2.14 Combining sorted queues. Create a static function that accepts two sorted queues as parameters and returns a queue formed by merging the queues into sorted order. 2.2.15 Mergesort from the bottom of the queue. Create a bottom-up mergesort implementation using the following method: Create N queues, each containing one of the things, given N items. Make a queue out of the N queues. Then, repeat Exercise 2.2.14's merging process on the first two queues, and finally, reinsert the combined queue.Repeat until there is just one queue in the queue of queues.

1. Build a web crawler function that starts with a URL representing a topic (a sport, your favorite film, a celebrity, a political issue, etc.) and outputs a list of at least 15 relevant URLs. The URLs can be pages within the original domain but should have a few outside the original domain.
17-14 C++ Instructions Write the definition of the function moveNthFront that takes as a parameter a positive integer, n. The function moves the nth element of the queue to the front. The order of the remaining elements remains unchanged. For example, suppose: queue = {5, 11, 34, 67, 43, 55} and n = 3. After a call to the function moveNthFront: queue = {34, 5, 11, 67, 43, 55} Add this function to the class queueType. Also, write a program (in main.cpp) to test your method.

Q__3.. ...Design a data structure that follows the constraints of a Least Recently Used (LRU) cache. Implement the LRUCache class: LRUCache(int capacity) Initialize the LRU cache with positive size capacity. int get(int key) Return the value of the key if the key exists, otherwise return -1. void put(int key, int value) Update the value of the key if the key exists. Otherwise, add the key-value pair to the cache. If the number of keys exceeds the capacity from this operation, evict the least recently used key. The functions get and put must each run in O(1) average time complexity. Example 1: Input ["LRUCache", "put", "put", "get", "put", "get", "put", "get", "get", "get"] [[2], [1, 1], [2, 2], [1], [3, 3], [2], [4, 4], [1], [3], [4]] Output [null, null, null, 1, null, -1, null, -1, 3, 4]...

8.13 LAB: Library book sorting Two sorted lists have been created, one implemented using a linked list (LinkedListLibrary linkedListLibrary) and the other implemented using the built-in Vector class (VectorLibrary vectorLibrary). Each list contains 100 books (title, ISBN number, author), sorted in ascending order by ISBN number. Complete main() by inserting a new book into each list using the respective LinkedListLibrary and VectorLibrary InsertSorted() methods and outputting the number of operations the computer must perform to insert the new book. Each InsertSorted() returns the number of operations the computer performs. Ex: If the input is: The Catcher in the Rye 9787543321724 J.D. Salinger the output is: Number of linked list operations: 1 Number of vector operations: 1 Which list do you think will require the most operations? Why?
