Which of these is an application of linked lists?

Answer:
Linked lists, a common data structure in computer science, are used in various applications due to their dynamic memory allocation and efficient insertion/deletion operations. Some common applications of linked lists include:

  1. Stacks and Queues: Linked lists are commonly used to implement stacks and queues. In a stack, elements are added and removed from the same end, while in a queue, elements are added at the rear and removed from the front. Linked lists provide an efficient way to implement these data structures.

  2. Memory Management: Linked lists are essential for memory management systems, such as malloc() and free() functions in C programming. These functions use linked lists to keep track of free memory blocks and allocate memory efficiently.

  3. Graphs and Trees: Linked lists are used to implement advanced data structures like graphs and trees. In a tree data structure, each node has a pointer to its children, which can be represented using linked lists.

  4. File Systems: Linked lists are used in file systems to maintain the list of files stored on a disk. Each entry in the linked list corresponds to a file, and they are linked together based on their properties.

  5. Music Players: Linked lists can be used in music players to create playlists. Each song can be represented as a node in the linked list, with pointers to the previous and next songs.

  6. Undo Functionality: Linked lists are used to implement the undo functionality in text editors or graphic design software. Each action is stored as a node in the linked list, allowing users to undo previous actions.

Overall, linked lists are versatile data structures that find applications in various fields of computer science and software development.
