Given the following unorderedLinkedList class, provide an implementation for the member function reverse. When the reverse function is called on an unorderedLinkedList object called mylist (e.g. mylist.reverse()), it will create a new unorderedLinkedList and insert the elements of mylist into the new list in reverse order and then return the new list. struct nodeType { int info; nodeType *link; }; class unorderedLinkedList { protected: nodeType *first; //pointer to the first node of the list public: unorderedLinkedList(); //Function to insert newItem at the beginning of the list. //Postcondition: first points to the new list, newItem is inserted at the beginning of the list, last points to the last node, and count is incremented by 1. void insertFirst(const int& newItem); //Function to insert newItem at the end of the list. //Postcondition: first points to the new list, newItem is inserted at the end of the list, //last points to the last node, and count is incremented by 1. void insertLast(const int& newItem); unorderedLinkedList* reverse() { //provide implementation of this function } };
