How does the single stack system work?

A single stack system is a data structure that uses a single stack to manage elements, typically following the Last In, First Out (LIFO) principle. In this system, elements are added to and removed from the top of the stack, allowing for efficient access and manipulation. It can be used for various applications, including function call management in programming, where each function call is pushed onto the stack and popped off when completed. The simplicity of a single stack system makes it easy to implement and understand, though it may have limitations in handling complex data relationships.
