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);…
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.

- C++ Programming Language ::::::: Redo the same functions this time as nonmember functions please : NOTE: You can add only one function into the linked list class get_at_position which will return value of element at given position. 1) Insert before tail : Insert a value into a simply linked list, such that it's location will be before tail. So if a list contains {1, 2, 3}, insert before tail value 9 is called, the list will become {1, 2, 9, 3}. 2) Insert before value : Insert a value into a simply linked list, such that it's location will be before a particular value. So if a list contains {1, 2, 3}, insert before 2 value 9 is called, the list will become {1, 9, 2, 3}. 3)Count common elements : Count common values between two simply linked lists.So if a list1 contains {1, 2, 3, 4, 5}, and list2 contains {1, 3, 4, 6}, number of common elements is 3. 4) Check if sorted : Check if elements of simply linked lists are sorted in ascending order or not.So if a list contains {1, 3, 7, 8, 9}…arrow_forwardWhen removing curNode from a doubly-linked list with at least 2 elements, the list's tail may be assigned with _____.
