Data structure and algorithms are two closely related concepts in computer science. A data structure is a way of organizing and storing data in a computer so that it can be accessed and modified efficiently. Examples of common data structures include arrays, linked lists, stacks, queues, and trees.
An algorithm is a step-by-step procedure for solving a problem or accomplishing a task. In computer science, algorithms are typically used to perform operations on data structures, such as searching for a particular piece of data, sorting a collection of data, or inserting or deleting data from a data structure.
Together, data structures and algorithms form the foundation of computer science, and they are essential for the design and implementation of efficient software systems. The study of data structures and algorithms involves the development of mathematical models to describe and analyze the performance of different approaches to solving computational problems, as well as the implementation of those approaches in programming languages.
