Question
Chapter 18, Problem 17RQE
The “inserting” a node refers the process of adding a node into a list, but not essentially at the end.
Program Plan Intro
Linked list:
Linked list is a linear and dynamic data structure which is used to organize data; it contains sequence of elements which are connected together in memory to form a chain. The every element of linked list is called as a node.
Liked list operations:
The basic linked list operations which are used to manipulate a list are as list below:
- Appending a node
- Inserting a node
- Deleting a node
- Traversing the list
- Destroying the list

6. __________ a node means adding it to the end of a list.
__________ a node means adding it to a list, but not necessarily to the end.
struct node{
int a;
struct node * nextptr;
};
Write two functions. One for inserting new values to a link list that uses the given node structure.
void insert(struct node **head, int value);
Second function is called to count the number of even numbers in the link list. It returns an integer that represents the number of even numbers.
int countEvenNumbers(struct node *head);
Write a C program that reads a number of integers from the user and insert those integers into a link list (use insert function). Later pass the head pointer of this link list to a function called countEvenNumbers. This function counts and returns the number of even numbers in the list. The returned value will be printed on the screen.
Note 1: Do not modify the function prototypes.

- Fill-in-the-Blank __________ a node means adding it to the end of a list.arrow_forward1 Singly Linked List A linked list is a data structure where elements are connected to form a chain where each node points to the next one in the order. Exercise: Given the code of the Node struct, implement a singly linked list with the following functionalities: • addFront: add an integer key to the front of the list. • remove: deletes the smallest number larger than or equal the passed integer and returns the deleted value. If no number is found, returns -1. All cases must be handled. You can define any helper method as needed. #include #include #define INF INT_MAX // indicates infinity value using namespace std; struct Node int key; Node next; Node(int key) { this->key - key; this->next- NULL; }; class SinglyLinkedList public: SinglyLinkedList () head - NULL; void addFront (Node* node) 1 int remove(int val) { private: Node head; }; int main() { SinglyLinkedList sLL - neu SinglyLinkedList (); Node* nodel = new Node (5); Node node2 - neu Node (13); Node node3 - nev Node(7);…arrow_forward2-) In a double linked list, the structure of a node is defined as follows: struct node { int employeeNo; char name[20]; struct node *next; structnode *prev; }node; the nodes in the list are sorted according to employeeNo in ascending order (from smaller to larger ). Write a function to insert a node with a given name and employeeNo into the list so that the list will remain the sorted. employeeNo değerine göre kiüçükten büyüğe sıralanmış bir çift bağlı liste olsun. Verilen bir isim ve employeeNo değerine sahip düğümü listeye sıra bozulmayacak şekilde ekleyen bir fonksyion yazınız.arrow_forward

- Remove Duplicates This function will receive a list of elements with duplicate elements, this function should remove the duplicate elements in the list and return a list without duplicate elements. The elements in the returned list must be in the same order that they were found in the list the function received. A duplicate element is an element found more than one time in the specified list.arrow_forwardA list that contains no data elements is said to be __________.arrow_forwardFunctions that look at a linked list but do not modify it are referred to as______________arrow_forward
