Step 1
Linked List:- A linked list is a linear data structure where each element is a separate object.
Array:- An Array is an ordered collection of items indexed by contiguous integers.

- Using Fundamental Data Structures Purpose: The purpose of this: Design and develop Applications that incorporate fundamental data structures such as: Singly Linked Lists Doubly Linked Lists Circularly Linked Lists Exercise 3 If your first name starts with a letter from A-J inclusively: Implement the clone() method for the CircularlyLinkedList class. Make sure to properly link the new chain of nodes. If your first name starts with a letter from K-Z inclusively: Let L1 and L2 be two circularly linked lists created as objects of CircularlyLinkedList class from Lesson. Write a method that returns true if L1 and L2 store the same sequence of elements (but perhaps with different starting points). Write the main method to test the new method. Hint: Try to find a matching alignment for the first node of one list.arrow_forward4. Explain about singly linked lists with example. Write algorithm for various operations.arrow_forwardHow nodes are defined (struct node (value count left right) #:mutable #:transparent) Write in Racket (traverse n) A traversal of a BST is an algorithm for “visiting” all node in the BST. The traversal must visit each node exactly once. In the case of a linked list, a traversal is trivial since the structure is linear: start at the head, move to the next node, and stop when you reach the tail. In the case of a BST, traversal must account for multiple child nodes and keep track of which subtrees have already been visited and which have not. There are three types of traversal: in-order, pre-order, and post-order. We will only implement in-order. The in-order traversal of a BST has the property that the node values will display in ascending or sorted order. The function can be defined either recursively or iteratively. Recursion is much simpler, so we’ll stick to that. Recursive Algorithm for In-Order Traversal of BST parameter: node n, the root of the tree…arrow_forward
- Provide an example of a type of dataset where standard stopword such as those provided by the nltk.corpus package might not be appropriate. Describe two techniques that you could utilise to identify common stopwords from a corpus of text.arrow_forwardJAVA Help: Mergesort Implement a natural merge sort for linked lists. (This is the method of choice for sorting linked lists because it uses no extra space and is guaranteed to be linearithmic.) During each iteration, natural merge sort works by scanning the list from the left to right identifying naturally sorted sub-lists and merging the sub-lists, and continue scanning further identifying and merging the sub-lists until the end of the list. Repeats the process until the entire list is sorted. Example: Unsorted list M -> E -> R -> G -> E -> S -> O -> R -> T -> E -> X -> A -> M -> P -> L -> E After first iteration: E - > M -> R -> E -> G -> S -> E -> O -> R -> T -> X -> A -> L -> M -> P -> E After second iteration: E -> E -> G -> M -> R -> S -> A -> E -> L -> M -> 0 -> P -> R -> T -> X -> E After third iteration: A -> E -> E -> E -> G…arrow_forwardDouble linked list in Java Double linked list Textbook reference Data structures and algorithms Micheal Goodricharrow_forward
