- Head Node (Dummy Head) must be existed with a Doubly linked list ? T or F?True or FalseA Doubly Linked List has a Header and Trailer sentinels to facilitate a more generic approach when adding and removing the head and tail nodes.Create a function that takes the first Node in a linked list as an input, reverses the list (destructively), and then returns the original Node.
- int F(node<int>&p){int c=0; while(p!=0){p=p->next; c++; } return c;} This function is a. return the number of items in the linked list b. return the number of items in a linked list and destroy the linked list c. None of these d. destroy the list and free all allocated nodesQ.4 What does the following function do for a given Linked List? (2)void fun1(struct node* head){if(head == NULL)return;fun1(head->next);printf("%d ", head->data);}C++ question 1.) Write an iterative routine that will take a string, go through each character of the string and enqueue the character if it is a punctuation (.,?!), else toss the character. When end of string is reached, then dequeue the characters, count how many punctuations are there, then print the count. 2.) Write a routine that would receive a pointer to the top of the linked list that has an integer for each node. Change all odd integers to even by adding one. But count the numbers you changed and print the count.
- Complete the following function where a node is perculated through a MaxHeap when given the value of the parent node (through the use of a linked list) void BinMaxHeap::percolateUp(BHNode *p) { }Think about the following example: A computer program builds and modifies a linked list like follows:Normally, the program would keep tabs on two unique nodes, which are as follows: An explanation of how to use the null reference in the linked list's node in two common circumstancesPart2: LinkedList implementation 1. Create a linked list of type String Not Object and name it as StudentName. 2. Add the following values to linked list above Jack Omar Jason. 3. Use addFirst to add the student Mary. 4. Use addLast to add the student Emily. 5. Print linked list using System.out.println(). 6. Print the size of the linked list. 7. Use removeLast. 8. Print the linked list using for loop for (String anobject: StudentName){…..} 9. Print the linked list using Iterator class. 10. Does linked list hava capacity function? 11. Create another linked list of type String Not Object and name it as TransferStudent. 12. Add the following values to TransferStudent linked list Sara Walter. 13. Add the content of linked list TransferStudent to the end of the linked list StudentName 14. Print StudentName. 15. Print TransferStudent. 16. What is the shortcoming of using Linked List?
- Question 30 If N represents the number of elements in the list, then the index-based add method of the LBList class is O(N). True False Question 31 A header node does not contain actual list information. True False Question 32 Any class that implements the Comparable interface must provide a compareTo method. True False Question 33 A SortedABList list can only be kept sorted based on the "natural order" of its elements. True False Question 34 O(N) is the order of growth execution time of the add operation when using the SortedArrayCollection class, assuming a collection size of N. True False Question 35 The iterator operation is required by the Iterable interface. Group of answer choices True False Question 36 O(N) is the order of growth execution time of the remove operation when using the SortedArrayCollection class, assuming a collection size of N. True False Question 37 O(N) is the order of growth execution time of the index-based add operation when…In a doubly linked list the first class is Node which we can create a new node with a given element. Its constructor also includes previous node reference prev and next node reference next. make a node object for the new element. Check if the index >= 0.If index is 0, make new node as head; else, make a temp node and iterate to the node previous to the index.If the previous node is not null, adjust the prev and next references. Print a message when the previous node is null. implement these 3 methods: insert_at_index(), delete_at_end(), display(). use these three functions above use this to name the items 1. insert_to_empty_list()2. insert_to_end()3. insert_at_index() 4. delete_at_start() 5. delete_at_end() . 6. display() let the output be OUTPUT: The list is emptyElement is: 3Element is: 10Element is: 20Element is: 30Element is: 35Element is: 38Element is: 40Element is: 50Element is: 60 Element is: 10Element is: 20Element is: 30Element is: 35Element is: 38Element is: 40Element…Question 11 If N represents the number of elements in the collection, then the contains method of the ArrayCollection class is O(1). True False Question 12 With the text's array-based list implementation, the set of stored elements is scattered about the array. True False Question 13 The add method of the LinkedCollection class places the new element at the beginning of the underlying linked list. True False Question 14 If N represents the number of elements in the list, then the index-based add method of the ABList class is O(N). True False Question 15 The attributes of a class that are used to determine equality of objects of the class are called the key attributes. True False Question 16 According to the text's specifications, a collection is a list. True False Question 17 O(1) is the order of growth execution time of the add operation when using the ArrayCollection class, assuming a collection size of N.
