Write a void function that takes a linked list of integers and interchanges data in the first node with that in the last node. The function will take a pointer to the head of the list. After the function is called, it will retrieve data stored in it, then find and retrieve data stored in the last node. The function will then interchange the data of the first node with that of the last node.
Note that your function will neither create nor destroy any nodes. It will simply interchange the data stored between the head and tail nodes. Place your function in a suitable test program.

What to Submit
Submit for this lab:
Implement the exchange_data function in main.cpp
You may add more functions that are needed to implement the above
Your code will not cause any runtime errors such as segmentation faults
Answer all three questions in the Problems Encountered & More section
Use visual aids to help you understand your plan for the function
Consider boundary cases, such as:
When the list is empty
When the list has only one node
You might want to rewrite or copy/type out other functions that are already implemented to solidify your understanding with linked list first
Suggestion: Change main.cpp to add more ways to test your reverse function implementation.
