This implementation differs in that it creates a new node instance per addition, each storing their supplied value and reference to the following node. ![]() On top of this it also provides constant time ‘O(1)’ guarantees when removing (popping) an element, as only a reference requires modification. Unlike the array implementation, using a Linked-List provides us with constant time ‘O(1)’ guarantees when adding an element, as no underlying array requires resizing. Using a Linked-List is tailor made to store the contents of a stack, handling the actions required with great performance results. The second example is more on par with what you might expect from a language implementation. Interface Stack Linked-List implementation The following examples solve the same problem, and as such I have created a simple interface that each implementation must fulfill.Ĭontractual agreements like this are great when you do not want the implementation details to effect the API that is available, allowing the user to use them interchangeably. This description can be abbreviated to LIFO, which stands for Last-In-First-Out.Īlthough you will most likely not have to implement such a structure for practical use-cases, it can be very useful to ‘look under the hood’ to gain a better understanding of what is going on.ĭoing so will make you more aware of when this data-structure can be best used. The stack is a fundamental data-structure used extensively in algorithm design and program implementation.Īt an abstract level it can be described very simply, as it only allows for addition (pushing) of new and removal (popping) of existing elements from the top of the stack.
