      Data structures are a collection of data values, the relationships among them, and the functions or operations that can be applied to the data. They provide a way to organize and store data in a way that is efficient and easy to access. Data structures are used in a variety of applications, including databases, operating systems, and computer graphics.

      Some common data structures include:

      • Arrays: An array is a collection of items of the same data type stored in contiguous memory locations.
      • Linked lists: A linked list is a linear collection of data elements, called nodes, where each node contains a value and a pointer to the next node in the list.
      • Stacks: A stack is a LIFO (Last In, First Out) data structure, meaning that the last element added to the stack is the first one to be removed.
      • Queues: A queue is a FIFO (First In, First Out) data structure, meaning that the first element added to the queue is the first one to be removed.
      • Trees: A tree is a hierarchical data structure composed of connected nodes, where each node can have zero or more child nodes and one parent node.
      • Graphs: A graph is a collection of nodes (vertices) connected by edges. Graphs are used to represent relationships between objects, such as roads between cities or friendships between people.

      Data structures are an essential part of computer science, and they are used in a wide variety of applications. By understanding data structures, you can write more efficient and effective programs.
