CPSC 221 Data Structures & Algorithms To implement the push function, we create a new node in the list and attach it as the new first element. To implement the pop function, we advance the top of the stack to the next object in the list (if there is one). An empty stack is represented by an empty linked list. To implement the class Stack we use the adapter design pattern. It maps the Stack functions onto the LinkedList class functions.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
