- Which of the following statements are true? A. Appending of elements to a dynamic list takes constant time. B. Row-wise traversal of 2-dimensional arrays is commonly faster than column-wise traversal. C. Tranversing an array is faster than traversing a linked list with the same number of entries. D. Node lookup time in a balanced binary search tres is O(1).Question 44 Computer Science A list of elements has a size of 100. Choose the operations where an ArrayList would be faster than a LinkedList. (Select all that apply) Question 5 options: removing from index 99 inserting at index 1 removing from index 4 inserting at index 4 Full explain this question and text typing work onlyWhich 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 array
- True/False Select true or false for the statements below. Explain your answers if you like to receive partial credit. 3) Which of the following is true about the insertBeforeCurrent function for a CircularLinked List (CLL) like you did in programming exercise 1?a. If the CLL is empty, you need to create the new node, set it to current, andhave its next pointer refer to itselfb. The worst case performance of the function is O(n)c. If you insert a new element with the same data value as the current node, theperformance improves to O(log n)Implement a program using Doubly LinkedList. Your doubly linked list should store information of students (Reg_no., Name, CGPA, city, age). Your program should provide following functionalities: Insert at Front Insert at Rear Insert in middle Delete from front Delete from rear Delete from middle Display all the data Data Structures in C++ Needed urgent i will thumb up for youTRUE or FALSE? Answer the following question and state the reason why: The delete operation only involves the removing of the node from the list without breaking the links created by the next node. You need an array to represent each node in a linked list. STL lists are also efficient at adding elements at their back because they have a built-in pointer to the last element in the list. A circular linked list has 2 node pointers. cout<<list.back()<<endl; = The back member function returns a reference to the last element in the list. In a Dynamic Stack, the pointer top stays at the head after a push operation. During a Pop operation in Static Stack, the elements are being moved one step up. In a dynamic implementation of stack, the pointer top has an initial value of null. In a dynamic stack, the node that was popped is deleted. In a dynamic stack, the pointer top stays at the head after push operation. STL function top returns a reference to element at the top of the…
- How many references must you changes to insert a node between two nodes in a double linked list. Show your answer with a drawing highlighting the new references. Assuming current is the reference of the next-to-last node in a linked list, write a statement that deletes the last node from the list. What is the time complexity of deleting a node from a linked listed? Is it faster than deleting a node from an array? Why?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.

Group of answer choices Unlike array, linked list can dynamically grow and shrink during runtime With linked list, we can ensure only the necessary amount of memory space is allocated at any time Accessing a specific element is more efficient with linked list Linked list is better equipped to handle a flexible data structureThis code by C to : 1- Create a sorted linked list using tenStudent array (copy from array into the linked list will be done). 2-Append an element to the end of a list and Details in the picture: >>>>>>>>>>>>>>>>>>>>>>> I want to update the code to : 1- Delete the last element from a list. 2- Delete the nth element from a list.
