UNIQUE WORK ONLY!!! C++ ONLY

Add and implement the following functions in LinkedList: //Add the elements in otherList to this list. void addAll(const LinkedList& otherList) //Remove all the elements in otherList from this list void removeAll(const LinkedList& otherList) //Retain the elements in this list if they are also in otherList void retainAll(const LinkedList& otherList) Add three function operators: +, -, and ^ for set union, difference, and intersection. Overload the = operator to perform a deep copy of a list. Add the [] operator for accessing/modifying an element. Use the Exercise 20_07 Template for Programming Exercise 20.7 in the book.
