Question

Describe the use of linked list.

Hint:

Use a linked list when you need efficient insertions and deletions in the middle of a sequence and you don't need fast random access to elements (which is an array's strength).

Answer 1

A linked list is a linear data structure used for storing a collection of elements. Its primary advantage is that the size of the list can be easily modified (elements can be added or removed) during program execution. Common uses include:

Implementing other data structures: Stacks, queues, and graphs can be efficiently implemented using linked lists.
Dynamic memory management: They are used in situations where the number of elements is unknown beforehand and can change frequently.
Music/Image viewers: The "next" and "previous" buttons often use a doubly linked list to navigate between items.
Undo functionality: The chain of "undo" operations in many applications is managed using a list-like structure.
