Answer 2

A circular linked list can be used for both stack and queue.

• A circular list is a linked list in which all nodes are connected to form a circle. There is no NULL at the end. A circular list may be a single circular list or a double circular list.
• Circular lists are useful in applications around the list over and over again. For example, when multiple applications are running on a PC, it is common for the operating system to run operating systems on a list and run them, giving each of them a slice of startup time, and then making them wait. while the CPU is supplied with another application.
• It is easy for the app to use a circular list so that when it reaches the end of the list it can rotate to the top of the list.
