Data structures are a fundamental concept in computer science. They are used to organize and store data efficiently. Here are some commonly used data structures:
- Arrays - A collection of elements of the same type.
- Linked Lists - A sequence of nodes where each node contains data and a reference to the next node.
- Stacks - A Last-In-First-Out (LIFO) data structure.
- Queues - A First-In-First-Out (FIFO) data structure.
- Trees - A hierarchical data structure consisting of nodes.
- Graphs - A collection of nodes (vertices) and edges connecting them.

Arrays are a fundamental data structure in programming. They store elements of the same type in a contiguous block of memory.
Linked lists are a dynamic data structure that allows efficient insertion and deletion of elements.
Stacks are used in various algorithms and data structures, such as the Tower of Hanoi.
Queues are commonly used in scenarios where elements need to be processed in the order they are received.
Trees are used to represent hierarchical relationships, such as file systems and organization charts.
Graphs are used to represent relationships between objects, such as social networks and transportation networks.
