- JAVA PROGRAMMING Q4.1: You have two sequences of mutually-comparable items to sort: The sequences are identical in terms of their sizes, their items, and the current (unsorted) order of those items. One sequence is in an array and the other is in a linked list. For the array and the link list, make an argument for why the quick sort would be best for one and the merge sort for the other. In the identified situation, give a quantitative answer based on big-O and other technical factors, not just a qualitative answer. Address the specifics of the two algorithms -- their operations, time efficiency, money use, etc. Assume no optimization Q4.2: Explain and/or illustrate the specific changes made in each pass of an Insertion Sort on the following data: 47 4 22 13 9 12Can i get this question with a detailed explanation Write a generic class called GenericStack<T> that represents a stack structure.

Currently stuck in a java problem and would appreciate the help! Question: You have probably heard about the deque (double-ended queue) data structure, which allows for efficient pushing and popping of elements from both the front and back of the queue. Depending on the implementation, it also allows for efficient random access to any index element of the queue as well. Now, we want you to bring this data structure up to the next level, the teque (triple-ended queue)! The teque supports the following four operations: push_back x: insert the element ?x into the back of the teque. push_front x: insert the element ?x into the front of the teque. push_middle x: insert the element ?x into the middle of the teque. The inserted element ?x now becomes the new middle element of the teque. If ?k is the size of the teque before the insertion, the insertion index for ?x is (?+1)/2(k+1)/2 (using 00-based indexing). get i: prints out the ?thith index element (00-based) of the teque.…

QImplement linked based list and ADTs in Java, fullfilling all conditions listed below Remember to use the code images below for data attributes: A LinkNode structure or class which will have two attributes - a data attribute and a pointer attribute to the next node. The data attribute of the LinkNode should be the Money class of Lab 1. A Singly Linked List class which will be composed of three attributes - a count attribute, a LinkedNode pointer/reference attribute pointing to the start of the list and a LinkedNode pointer/reference attribute pointing to the end of the list. Since this is a class, make sure all these attributes are private. The attribute names for the Node and Linked List are the words in bold in #1 and #2. For the Linked List, implement the most common linked-list behaviors as explained in class - getters/setters/constructors/destructors for the attributes of the class, (a) create new list, (b) add data, (c) delete data, (d) find data, (e) count of data items in…

- Select true or false for the statements below. Explain your answers if you like to receive partial credit 4) Given a stack implemented as a standard linked list (only a head pointer) with O(1)push and O(1) pop, and the following functions are performed in sequence:Push(“Charmander”), Push(“Squirtle”), Push(“Bulbasaur”), Pop(), Push(“Larvitar”),Push(“Eevee”), Pop(), Pop()Which of the following is true after all the functions are executed?a. Charmander and Squirtle will be the only elements left on the stackb. The head node will be pointing to Charmanderc. If you Push(“Pikachu”), it will be the last node of the linked listPlease implement this function: void swap(int pos1, int pos2) {}. There's an answer from the previous teacher but he added '' node** hRef " in the function (see below) please correct without the href. For LinkedList, to maintain integrity of data in the structure, you are not to swap directly the element, nor remove a node. Instead, you are to only change the nodes' next pointers. PLEASE CORRECT THIS ONE void swap(node** hRef, int pos1, int pos2) { if (pos1 == pos2) return; node *prevNode1 = NULL; node* currNode1 = *hRef; while (currNode1 && currNode1->index != pos1) { prevNode1 = currNode1; currNode1 = currNode1->next; } node *prevNode2 = NULL; node *currNode2 = *hRef; while (currNode2 && currNode2->index != pos2) { prevNode2 = currNode2; currNode2 = currNode2->next; } if (currNode1 == NULL || currNode2 == NULL) return; if (prevNode1 != NULL) prevNode1->next =…Using java, write an easier version of a linked list with only a couple of the normal linked list functions and the ability to generate and utilize a list of ints. The data type of the connection to the following node can be just Node, and the data element can be just an int. You will need a reference like (Java) or either a reference to the first node, as well as one to the last node. (Answer the following questions) 1) Create a method or function that accepts an integer, constructs a node with that integer as its data value, and then includes the node to the end of the list. If the new node is the first one, this function will also need to update the reference to the first node. This function will need to update the reference to the final node. Consider how to insert the new node following the previous last node, and keep in mind that the next reference for the list's last node should be null. 2) Create a different method or function that iteratively explores the list, printing…
