3. Coding Exercise (20 points ).

Using good coding practices,  design your own Linked List of  int types.   It will consist of classes List,  Node,   and Iterator granting friendship and defining functions as needed. Write constructors, destructors,  and  all necessary member functions such as insert, erase, increment and decrement operators, operator* to dereference,  as well as operator== and operator!= to check whether two iterators are pointing to the same element. You will then use this list to write the following member functions :

• List::reverse to reverse your nodes
• List::push front to add a value to the beginning of a list
• List::sort to sort the elements of a linked list (without copying them into a vector or another data type)
• List::merge which accepts another List object and merges the two lists into one, alternating elements from each list such that merging 1 7 12 and 8 3 11 2 2 1 yields the list 1 8 7 3 12 11 2 2

Write a main function to test your list such that it follows the output shown in Figure 1. Compile your code  and run your program to check for compile-time errors and logic errors. Submit your header files and source codes to ccle.ucla.edu in separate files.
