Everything You Need to Know About Linked Lists

🔗Linked lists are the first serious data structure you learn about and are more complex than arrays.

📚Each node in a linked list contains an item of data and a reference to the next node.

➕Insertion and deletion operations in linked lists are efficient, making them suitable for dynamic data storage.

📝Linked lists do not provide random access, so accessing elements requires sequentially traversing the list.

⛓️Doubly linked lists have nodes that point to both the next and the previous node, allowing for more flexibility.

What is the main difference between arrays and linked lists?

—Linked lists do not require contiguous memory, unlike arrays.

What is a node in a linked list?

—A node in a linked list is a data structure that contains an item of data and a reference to the next node.

Are linked lists suitable for dynamic data storage?

—Yes, linked lists are efficient for operations like insertion and deletion, making them suitable for dynamic data storage.

Can linked lists provide random access to elements?

—No, linked lists require sequential traversal to access elements, so random access is not possible.

What are doubly linked lists?

—Doubly linked lists are a type of linked list where each node has references to both the next and previous nodes.
