Implement the (class) Linked List with Dummy head node to create a list of integers. You need to provide the implementation of the member functions as described in the following.

class HList

{

private:

Node * head;

public:

HList();

// Checks if the list is empty or not

bool emptyList();

// Inserts a new node with value ‘newV’ after node with value ‘oldV’in the list

void insert_after(int oldV, int newV);

// Inserts a new node at the start of the list

void insert_begin(int value);

// Inserts a new node at the end of the list

void insert_end(int value);

// Deletes a node from position ‘pos’ of the list

void deleteNode(int pos);

// Deletes a node from the beginning of the list

void delete_begin();

// Deletes a node from the end of the list

void delete_end();

// Displays the values stored in the list

void traverse();

};
