Linked lists are dynamic data structures where elements are connected via pointers. Unlike arrays, they allow efficient insertion and deletion.
Stacks follow LIFO (Last In First Out). They are used in recursion, undo operations, and expression evaluation.
Queues follow FIFO (First In First Out). They are used in scheduling and buffering.
Key topics:
- Singly and doubly linked lists
- Stack operations (push, pop)
- Queue operations (enqueue, dequeue)
Understanding these structures improves your problem-solving skills significantly.
