Question

Accepted Answer

Data structures are ways of organizing and storing data in a computer so that it can be accessed and used efficiently.

Types of data structures include arrays, linked lists, stacks, queues, trees, graphs, and hash tables.
Arrays are a collection of elements stored in contiguous memory locations, accessed using an index.
Linked lists are a series of nodes where each node contains data and a reference to the next node.
Stacks follow the Last In First Out (LIFO) principle, where elements are added and removed from the top.
Queues follow the First In First Out (FIFO) principle, where elements are added at the rear and removed from the front.
Trees are hierarchical data structures with a root node and child nodes.
Graphs consist of nodes connected by edges, representing relationships between entities.
Hash tables use a hash function to map keys to values, allowing for efficient retrieval of data.
