__________ a node means adding it to a list, but not necessarily to the end.

1 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.
