What are the different types of data structures?

Data structures can be classified into two main types: primitive and non-primitive. Primitive types include integers, floats, and characters, while non-primitive types include arrays, linked lists, stacks, queues, trees, and graphs.

Can you explain arrays and linked lists?

Sure! An array is a collection of elements identified by index or key, allowing for fast access. A linked list, on the other hand, consists of nodes where each node contains data and a reference to the next node, allowing for dynamic memory allocation.

What are the advantages of using a linked list over an array?

Linked lists offer dynamic sizing, easier insertions and deletions, and efficient memory usage, while arrays have fixed sizes and require shifting elements for modifications.

What about stacks and queues?

Stacks are LIFO (Last In, First Out) structures, while queues are FIFO (First In, First Out). Stacks are used for backtracking, and queues are used in scheduling tasks.
