Linked lists are dynamic data structures that consist of nodes, where each node contains data and a reference to the next node. Linked lists provide flexibility in terms of size, as memory can be allocated or deallocated as needed. However, accessing elements in a linked list requires traversing the list, which can be slower compared to arrays.
Stacks: LIFO Principle in Action
Stacks follow the Last-In-First-Out (LIFO) principle, where the last element pushed onto the stack is the first one to be popped out. They can be implemented using arrays or linked lists. Stacks are used in various applications, such as function call stacks, undo-redo operations, and expression evaluation.
Queues: FIFO Principle at Work
Queues follow the First-In-First-Out (FIFO) principle, where the first element enqueued is the first one to be dequeued. They can also be implemented using arrays or linked lists. Queues are used in scenarios where the order of processing is important, such as job scheduling, printer spooling, and message queues.
Trees: Hierarchical Structures
Trees are hierarchical data structures that consist of nodes connected by edges. Each node can have zero or more child nodes. Trees are used to represent hierarchical relationships, such as file systems, organization charts, and HTML/XML documents. They provide efficient searching, insertion, and deletion operations.
