Q5 A double-linked list 10 Points Define a struct Node to represent a node in a double-linked list that stores a string as data. Write a function that inserts a node to the head of the linked list. In particular, your function should meet the following requirements: Takes two arguments: a reference to the pointer to the current first node (i.e. Node*& head) in the double-linked list and a string value, Does not return any value, and Creates the new node in the heap with the given data value and sets it as the new head of the list. Make sure you correctly handle the case of an empty list (i.e. if head is nullptr or NULL oro).
