When diving into data structures, the linked list is one of the most foundational yet intricate concepts. Unlike arrays, where elements are stored in contiguous memory locations, linked lists rely on nodes that are connected via pointers. This unique architecture makes linked lists both powerful and challenging to grasp for beginners. Visualizing them, however, can make learning significantly easier.

What Is a Linked List?

A linked list is a linear data structure where each element (called a node) contains two parts:

1. Data: The actual value stored in the node.
2. Pointer/Link: A reference to the next node in the sequence.

Types of linked lists include:

• Singly Linked List: Each node points to the next node.
• Doubly Linked List: Nodes have pointers to both the next and previous nodes.
• Circular Linked List: The last node points back to the first, forming a loop.
