- Select true or false for the statements below. Explain your answers if you like to receive partial credit 10) Which of the following is true about the linked list functions where the linked list onlycontains a head pointer?a. If the linked list is ordered, you can use binary search and improve theperformance to O(log n)b. The worst case performance of the delete function is in the same Big-Ocategory as the worst case performance of the delete function with anunordered arrayc. If the node you are deleting is at the end of the list, the performance is O(1)Which of the following structures would be the most efficient to use if you wanted to establish a priority queue for quick retrieval? Choose one: a. a doubly linked list that is sorted O b. array of ordered elements a. unordered singly linked list b. unordered singly linked list c. unordered singly linked O d. an unsorted arrayUse the standard linked list below to answer True/False statements 9-12: 9) The “head” pointer of this list is pointing to Node 4 10) If we called “insert(5)”, the new node’s “next” pointer will point to Node 8 11) If we called “delete(10)”, Node 7’s “next” pointer will point to Node 8 12) If we called “search(20)”, the “head” pointer will be at Node 4 after the search function ends
- q9) In which of the following linked list there will be no beginning and ending? a. Depends on the Problem. b. Single Linked List. c. Double Linked List. d. Circular Linked List.When a list is implemented using an array, which of the following is FALSE? Select one: A.If the size of the array is insufficient, there is a need to copy the whole list to a new array B.The new node inserted might cause shifting of the existing elements C.The memory allocation can be very inefficient D.The insertion of a new element is proportional to the size of the listWhich of the following statement is not true about the doubly linked list? A. We can traverse in both the directions. B. It requires extra space C. Implementation of doubly linked list is easier than the singly linked list D. It stores the addresses of the next and the previous node
- The bubble sort algorithm discussed in class is used to sort the following sequence of integers: 2 16 38 9 4 14 How many passes must the algorithm perform to guarantee the entire sequence is sorted? What is the list obtained after the first pass? What is the list obtained after the third pass? What is the list obtained after the final pass?i have written this code to make all arrangments of a word in a dictionary can you modifiy it so that it generates words with doublcates letters also. so if i pass ABCD and let assume our dictionary has the word(ADD) so ADD will be one of the words in the list. public static List<String> findValidWords(List<String> dict, char letters[]) { int[] avail = new int[26]; for (char c : letters) { int index = c - 'A'; avail[index]++; } ArrayList<String> result = new ArrayList<>(); for (String word : dict) { int[] count = new int[26]; boolean ok = true; for (char c : word.toCharArray()) { int index = c - 'A'; count[index]++; if (count[index] > avail[index]) { ok = false; break; } } if (ok) { result.add(word); } } return…Implement two out of three of the basic sorting algorithms - Bubble Sort, Selection Sort, and Insertion Sort - in a generic List. Initial code to be completed: #include <iostream>#include "linkedlist.h" void bubbleSort(List*);void selectionSort(List*);void insertionSort(List*); /** * This activity is focused on using Arrays and Linked Lists as two different * implementations of List. It follows that you are only to use the methods of * List and not of the specific array or linkedlist. */int main(void) { // WARNING!

- When a list is implemented using an array, which of the following is FALSE? Select one: A.If the size of the array is insufficient, it whole list will be automatically copied to a new array B.The new node inserted might cause shifting of the existing elements C.The insertion of a new element is proportional to the size of the list D.The memory allocation can be very inefficientComplete the below code so the program will : - Receive a word from user - Then, transfers it into a doubly linked list (for example if the word is Hello, then the doubly linked list would have 5. nodes: H, e, l , l , o) - Finally, uses insertion-sort to scramble it into descending order. - Example: If the word is "Hello", the output should look like below: - List after insertion sort: o l l h e Some of the code has been written below in main.py class Node:def __init__(self, data):self.data = dataself.next = Noneself.prev = None# Empty Doubly Linked Listclass DoublyLinkedList:def __init__(self):self.head = None# Inserts a new node on the front of listdef append(self, new_data): if self.head is None:self.head = new_dataself.tail = new_dataelse:self.tail.next = new_datanew_data.prev = self.tailself.tail = new_datadef printList(self):if(self.head is None):print('Empty!')else:node = self.headwhile(node is not None):print(node.data),node = node.next print()def remove(self,…there are similar questions please come up with an original answer because the questions are slighty different, thank you. FREE = 2 B FIRST = 5 D SHOW CHANGES IN DATA AND NEXT MEMBERS OF THE ARRAY AND THE VALUES OF FIRST AND FREE AFTER H IS INSERTED INTO THE LINKED LIST SO THE RESULTING LIST IS IN ALPHABETICAL ORDER.
