1. What is a data structure?
A data structure is a way of organizing and storing data so that it can be efficiently accessed and modified.
2. What are the types of data structures?
Data structures are broadly categorized into linear and non-linear types.
3. What are linear data structures?
Linear data structures store elements sequentially, where each element is connected to the previous and next elements.
4. What are examples of linear data structures?
Examples include:
- Array: A fixed-size collection of elements stored in contiguous memory.
- Linked List: A collection of nodes, each containing data and a reference to the next node.
- Stack: A Last-In-First-Out (LIFO) structure where elements are added and removed from the top.
- Queue: A First-In-First-Out (FIFO) structure where elements are added at the rear and removed from the front.
5. What are non-linear data structures?
Non-linear data structures allow elements to be connected in multiple ways rather than sequentially.
6. What are examples of non-linear data structures?
Examples include:
- Tree: A hierarchical structure where each node is connected to child nodes.
- Graph: A collection of vertices connected by edges, useful in networks.
- Hash Table: A structure that maps keys to values using a hash function for fast access.
7. Where are these data structures used in real-world applications?
- Queues are used for task scheduling.
- Graphs are used in network routing and social media connections.
- Trees help in organizing hierarchical data like file systems.
