Components in computer science and programming that enable the efficient organization, storage, and manipulation of data. They provide a systematic way of managing data, allowing programmers to access and process information quickly and effectively. Here's a brief overview of some common data structures:
  • Arrays: Arrays are a basic data structure that stores elements of the same type in contiguous memory locations. They offer fast access to elements via indexing but have a fixed size.
  • Linked Lists: Linked lists are a linear data structure consisting of nodes, each containing a data element and a reference (or pointer) to the next node in the sequence. They allow for dynamic memory allocation and efficient insertion and deletion operations.
  • Stacks: Stacks are a collection of elements that follow the Last In, First Out (LIFO) principle. Elements are added and removed from the top of the stack, making it useful for implementing algorithms like expression evaluation and backtracking.
  • Queues: Queues are similar to stacks but follow the First In, First Out (FIFO) principle. Elements are added to the rear (enqueue) and removed from the front (dequeue) of the queue. They are commonly used in scheduling, buffering, and breadth-first search algorithms.
  • Trees: Trees are hierarchical data structures consisting of nodes conn Chinese Overseas Asia Number ected by edges. They have a root node and may have one or more child nodes, forming a tree-like structure. Common types of trees include binary trees, binary search trees, and AVL trees.



  • Graphs: Graphs are non-linear data structures consisting of vertices (nodes) connected by edges (links). They are used to model relationships between objects and are widely used in network routing, social networks, and optimization problems.
  • Hash Tables: Hash tables are a data structure that stores key-value pairs and uses a hash function to map keys to indices in an array. They offer fast insertion, deletion, and retrieval operations and are used in associative arrays, caches, and databases.

Understanding and mastering these data structures is essential for writing efficient and scalable code, as they provide the foundation for solving a wide range of computational problems in various domains of computer science.
