The last node in the LinkedList is the tail. The “Head” of the LinkedList is a pointer that contains the address of the first element in the LinkedList.

This arrangement is necessary as the data in LinkedList is stored in non-contiguous locations, unlike Arrays. Each node has two parts, the first part stores the data and the second part has a reference or pointer or address of the next node in the LinkedList. Further examination would be required, so there you have your next post.Given below is the general Layout of LinkedList:Īs shown in the above representation of LinkedList, each item in the LinkedList is the “Node”.

I remember seeing in reflector once that it uses an Array internally as well, which would defeat the whole purpose if not done correctly. Microsoft's collection namespaces are a mess. You could also elaborate on the further differences between a Linked List and an Array or an Array based List (like List in the. Public void AddAtLast(this LinkedList list, object data) The methods are pretty much identical per instance. That means you are now allocating memory for 100,000 methods. So number of objects multiplied by the number of methods. That memory would need to include space for 10,000 * number of methods. You would have to allocate memory for 10,000 LinkedList objects. Let's say you created 10,000 LinkedList instances. Even better than static, might be Extension methods, so they still feel attached and you can call it with myLinkedList.Method(), but you would just have to make your members "internal" instead of "private" for extension methods to have access to head and current. However, your methods are not unique per instance. Not that memory matters too much to some, but each linked list created will have to allocate space for your methods. Here is the node class which has 2 properties: Because it stores reference of next/previous nodes. So linked list can be used where there is an unknown number of data that needs to be stored at run time.ĭisadvantage of linked list is that it takes more space than array. Unlike in array where length of array is predefined, we can add dynamic number of data in linked list without worrying about size of linked list. Main advantage of linked list is that it is a dynamic data structure. In this article, I'll explain implementation of only singly linked list. Circular linked list can be singly linked list or doubly linked list.

In this, last node's next reference will be null. Singly Linked List: A singly linked list is a list which has a value(data) and a reference to next node.Types of Linked Listsīasically, there are 3 types of linked lists. The very first node is called as Head and last element has reference to null value. Element is called as Node.Įach element has value(data) and reference of next node. Here, I'll explain the core implementation of Linked List. However, Microsoft provides strongly typed linked list LinkedList(T) in namespace.
