Datastructure
A data structure is a way of organizing data in memory to enable efficient access and modification. It defines how data is stored and how operations are performed, often corresponding to an abstract data type that specifies behavior while hiding implementation details.
Common data structures include arrays, linked lists, stacks, queues, trees, graphs, and hash tables. Arrays store
Operations such as insert, delete, search, and traverse have different performance profiles. Time and space costs
Design considerations include memory usage, cache locality, mutation frequency, and expected data size. Some structures are
Data structures are central to algorithms and systems, from databases and file systems to compilers and simulations.
