Using the textbook,class examples,or on line research, make a linked list template class that implements the basic linked list operations:

• appending a node
• traversing the list
• inserting a node
• deleting a node
• destroying the list

Use a separate class template for the data type of the node. The constructor should store data in thevaluemember and set thenextpointer to nullptr.

The attached files contains an updated version of theContactclass seen previously in example programs. Several overloaded operators have been implemented, including <, >, ==, <<, and >>. The main program illustrates usage of the >> and << operators with an object of the class.

make a menu-driven program with the following options (program should loop until the exit option is selected):

1. Add a contact
2. Delete a contact
3. Display all contacts
4. Exit

All contacts should be sorted by name, then email. You are free to implement this in any manner you choose (although I would suggest "inserting a node"). Skip a line between contacts when displaying all contacts. When deleting a contact, the user should provide both a name and an email to remove (HINT: make a dummy object with those values and then traverse the list using the == operator to check for a match).
