Hello i need help solving this problem in Starting Out With C++ by Tony Gaddis edition 9 chapter 18 programming challange 14.

Overloaded the [ ] operator. This will give the linked list the ability to access nodes using a subscript, like an array. The subscript 0 will reference the first node in the list, the subscript 1 will reference the second node in the list, and so forth. The subscript of the last node will be the number of nodes minus 1. If an invalid subscript is used, the function should throw an exception.

Thank you.
