The material from Ch$1$ ~ $6$ of the textbook can help you tremendously. The chapter $6$ of the text book is focus on Template class. You need to spend more time on understanding template prefix, template parameter, typename and etc. I call these $($template prefix, template parameter, $.$etc.$)$ are template stuff. Implementing the template class almost the same as implementing a regular class, but you need to add the template stuff in the file and save the file name with a template extension. If you feel confusion with the template stuff in a file you can implement the class as a regular class and add the template stuff at the end of implementation. You are welcome to use more advance skills than the techniques introduce in the textbook to do the assignment.
