Data Structures & Algorithms Introduction to Data Structures A data structure is a way of storing and organizing data in a computer so it can be used efficiently. It defines how data is arranged, how elements are connected, and what operations can be performed on that data. The main goal is to make accessing, updating, and managing information faster and easier, especially when working with large amounts of data or complex applications. Key points about data structures: Organization: Data can be arranged in a linear format (like arrays or linked lists, where elements follow a sequence) or a non-linear format (like trees or graphs, where elements have hierarchical or network-like relationships). A well-organized structure makes data easier to manage and process. Efficiency: The right choice of data structure can drastically improve the speed of operations such as searching, sorting, inserting, and deleting data. For example, a hash table can perform lookups much faster th...
