Step by step
Solved in 3 steps
- Design data structures: present five data structures including B-tree for big data (you find data), for sorting algorithms. In this project, you will implement and analyze the following. Median finding, Order Statistics, and Quick Sort: In this project, you will implement the median-finding algorithms. The user should be able to select the "k”, i.e., the rank of the number desired as output (k = n/2 is the median). You should also be able to select groups of 3, 5, 7, etc. in the linear-time median finding algorithm and be able to compare the performance of each. Also, implement the randomized median finding algorithm and compare it against the linear-time one. Implement quick sorting using both algorithms and compare the performances of these different versions.Java - This project will allow you to compare & contrast different 4 sorting techniques, the last of which will be up to you to select. You will implement the following: Bubble Sort (pair-wise) Bubble Sort (list-wise) [This is the selection sort] Merge Sort Your choice (candidates are the heap, quick, shell, cocktail, bucket, or radix sorts) [These will require independent research) General rules: Structures can be static or dynamic You are not allowed to use built in methods that are direct or indirect requirements for this project – You cannot use ANY built in sorting functions - I/O (System.in/out *) are ok. All compare/swap/move methods must be your own. (You can use string compares) Your program will be sorting names – you need at least 100 unique names (you can use the 50 given in project #3) – read them into the program in a random fashion (i.e. not in any kind of alpha order). *The more names you have, the easier it is to see trends in speed. All sorts will be from…Use the following node definition for this problem.struct NodeInt32{int32_t value; NodeInt32* next;} Write a function which searches a non-empty linked list for a target value. Its exact signature should be: NodeInt32* find(NodeInt32* head, int32_t target); The function should return the first node whose value equals target. If the target is not found in the list, then the function should return NULL.
- Coding language: C++. (Try to avoid linked lists if possible please). Add comments. Thanks. • Each functionality component must be implemented as a separate function, though the function does not need to be declared and defined separately • No global variables are allowed • No separate.hor.hpp are allowed • You may not use any of the hash tables, or hashing functions provided by the STL or Boost library to implement your hash table • Appropriate, informative messages must be provided for prompts and outputs You must implement a hash table using the Double Hashing collision strategy and the mid-square base 10 hashing function with an R of 2. Your collision strategy must be implemented as a separate function, though it may be implemented inside your insert/search/delete functions, and should halt an insert / search/delete functions, and should halt an insert/search/delete after table size number of collisions. Your hash function must be implemented as a separate function. Your hash table…Project 2: Singly-Linked List The purpose of this assignment is to assess your ability to: ▪Implement sequential search algorithms for linked list structures ▪Implement sequential abstract data types using linked data ▪Analyze and compare algorithms for efficiency using Big-O notation For this assignment, you will implement a singly-linked node class. Use your singly-linked node to implement a singly-linked list class that maintains its elements in ascending order. The SinglyLinkedList class is defined by the following data: ▪A node pointer to the front and the tail of the list Implement the following methods in your class: ▪A default constructor list<T> myList ▪A copy constructor list<T> myList(aList) ▪Access to first elementmyList.front() ▪Access to last elementmyList.back() ▪Insert value myList.insert(val) ▪Remove value at frontmyList.pop_front() ▪Remove value at tailmyList.pop_back() ▪Determine if emptymyList.empty() ▪Return # of elementsmyList.size() ▪Reverse order of…card_t * moveCardBack (card t *head); The moveCardBack function will take the card in front of the pile and place it in the back. In coding terms, you are taking the head of the linked list and moving it to the end. The function has one parameter which is the head of the linked list. After moving the card to the back, the function returns the new head of the linked list.
- The Set<T> API has the following methods: void add(T) boolean contains(T) boolean remove(T) The most space efficient implementation of a SET API is:struct remove_from_front_of_dll { // Function takes no parameters, removes the book at the front of a doubly // linked list, and returns nothing. void operator()(const Book& unused) { //// TO-DO (13) |||| // Write the lines of code to remove the book at the front of "my_dll", // // Remember, attempting to remove an element from an empty data structure is // a logic error. Include code to avoid that. ///// END-TO-DO (13) //// } std::list& my_dll; };Which of the following code segments can be used as a constructor for a node in a linked list. Each node contains a pointer to the next node called next and also has a String called data. O public node () { next = 0; } } public node () { next = "";} } O public node () { next = null; } } O public node () { next = new node(); }
- @6 The Reference-based Linked Lists: Select all of the following statements that are true. options: As a singly linked list's node references both its predecessor and its successor, it is easily possible to traverse such a list in both directions. According to the terminology introduced in class, the head reference variable in a singly linked list object references the list's first node. According to the terminology introduced in class, in a doubly linked list, each node references both the head and tail node. In a double-ended singly linked list, the tail reference variable provides access to the entire list. In a circular linked list, the last node references the first node.Problem You want to implement a custom class that mimics the behavior of a common built-in container type, such as a list or dictionary. However, you're not entirely sure what methods need to be implemented to do it.II. Project Description Parts Catalog This project builds a parts catalog using a B-tree for storage. Introduction: Today a parts catalog would be built using a database for storage. Databases are very versatile in their ability to store and retrieve data. In this project, you will build a parts catalog system as a single-user system without the use of a database. Instead, you will create a B+-tree and store the parts data in it. Overview: This project consists of two parts: a B+-tree for storing parts data and a user interface for accessing the data. These two parts should be independent, so that changing to another storage system or another user interface is not too difficult. Your project should allow the user to maintain a parts catalog. A flat-file of part data will be provided. Your program should begin by loading data from the flat-file into a B+-tree. Once loaded, the user can query for a particular part number, display the next 10 parts, modify the description of a part, add…
