Please answer question in In C++,

Node class represents a single element of the linked list.

class Node { public: string key; Node* next; }; 

Write a Function to add a New Node with key value from parameter string 'item' to the head of a list:

Node* InsertItem(Node* List, string item); 

Write a Function to print items in linked list:

void PrintList(Node* List); 

Test the basic functionality of the linked list by reading in lines from input, and adding the lines to the linked list until a blank line is input. Then print out the linked list.

while (true){ getline(cin, line); if (line.empty()) { break; } //// Insert data from line into a linked list. } //// Print Linked List 

Finally write a Function to insert item after the item having a specific key value:

void InsertAfter(Node* List, string key, string item);

I know this is a difficult question, so your response is greatly appreciated !
