What are the different types of data structures?

The different types of data structures are:

1. Arrays: A collection of elements of the same data type, stored in contiguous memory locations.

2. Linked Lists: A sequence of nodes where each node contains data and a reference to the next node.

3. Stacks: A Last-In-First-Out (LIFO) data structure where elements are added and removed from the same end.

4. Queues: A First-In-First-Out (FIFO) data structure where elements are added at one end and removed from the other end.

5. Trees: A hierarchical data structure with a root node and child nodes, where each node can have multiple children.

6. Graphs: A collection of nodes (vertices) connected by edges, representing relationships between entities.

7. Hash Tables: A data structure that uses a hash function to map keys to values, allowing for efficient retrieval and storage.

8. Heaps: A complete binary tree where each node is either greater than or equal to (max heap) or less than or equal to (min heap) its child nodes.

9. Tries: A tree-like data structure used to store strings, where each node represents a character and the path from the root to a node forms a string.

10. Sets: A collection of unique elements with no specific order.

11. Graphs: A collection of nodes (vertices) connected by edges, representing relationships between entities.

These are some of the commonly used data structures, each with its own advantages and use cases.
