Given a linked list of node declared as follows, write a condition that checks if pointer p points to the first node of a linked list of node named list. struct node int number; struct node "next; 3;

Every time you write a non-const member function for a linked list, you should always think about if that function is preserving your class invariants. Group of answer choices A. True B. False

Suppose a node of a doubly linked list is defined as follows:  struct Node{  int data;  struct Node* next;  struct Node* prev;  };  Write the function definition of the function deleteElement as presented below. This function deletes a node at position n from a doubly linked list.  struct Node* deleteElement(struct Node* head, int n){  //write the function definition  }

T/F: All Linked Lists must have head node.

Assume a linked list contains following integers: 7, 2, 9, 5, 8, 3, 15 and the pointer head is pointing to the first node of the list. What will be the value of variable a after the following statements are executed: Node<int> *curNode=head; Node<int> *aNode; int s; while(curNode!=NULL){ {       aNode=curNode;       curNode=curNode->getNext(); } s=aNode->getItem();   A. 15 B. 3 C. 7 D. 2

Project 2: Singly-Linked List The purpose of this assignment is to assess your ability to: ▪Implement sequential search algorithms for linked list structures ▪Implement sequential abstract data types using linked data ▪Analyze and compare algorithms for efficiency using Big-O notation For this assignment, you will implement a singly-linked node class. Use your singly-linked node to implement a singly-linked list class that maintains its elements in ascending order. The SinglyLinkedList class is defined by the following data: ▪A node pointer to the front and the tail of the list Implement the following methods in your class: ▪A default constructor list<T> myList ▪A copy constructor list<T> myList(aList) ▪Access to first elementmyList.front() ▪Access to last elementmyList.back() ▪Insert value myList.insert(val) ▪Remove value at frontmyList.pop_front() ▪Remove value at tailmyList.pop_back() ▪Determine if emptymyList.empty() ▪Return # of elementsmyList.size() ▪Reverse order of…

struct node{int num;node *next, *before;};start 18 27 36 45 54 63 The above-linked list is made of nodes of the type struct ex. Your task is now to Write a complete function code to a. Find the sum of all the values of the node in the linked list. b. Print the values in the linked list in reverse order. Use a temporary pointer temp for a and b. i dont need a full code just the list part

Anybody??

program Linked List: modify the following program to make a node containing data values of int, char, and string. #include <iostream> using namespace std; struct node { int data; struct Node *next; }; struct Node* head = nullptr;//or Null or 0; void insert(int new_data) { struct Node* new_node=(struct Node*) new(struct Node); new_mode->data=new_data; new_mode->next=head; head=new_node; } void display() { struct Node* ptr; ptr=head; while(ptr ! = NULL) {   cout<<ptr->data<<""; ptr=ptr->next; } } int main() { insert{2}; display{}; return0; }
