using this code how can i implement the remove function, I am not sure how to access the value being passed by reference

#ifndef __DOUBLYLINKEDLIST_H__ #define __DOUBLYLINKEDLIST_H__ // // #include #include using namespace std;

class DoublyLinkedList { public: DoublyLinkedList(); ~DoublyLinkedList(); void append (const string& s); void insertBefore (const string& s); void insertAfter (const string& s); void remove (const string& s); bool empty(); void begin(); void end(); bool next(); bool prev(); bool find(const string& s); const std::string& getData() const;
