35. Sets, stacks, queues
The chapter focuses on fundamental data structures in Python, including sets, stacks, and queues, highlighting their properties and applications. It emphasizes the importance of understanding how these data structures can optimize processing and manipulation of data efficiently. The chapter provides practical examples and pseudo code to demonstrate the usage of these structures in algorithm development.

What we have learnt
- Sets are collections of unique values and support basic set operations.
- Stacks follow a last-in, first-out (LIFO) principle, useful for managing recursive function calls.
- Queues adhere to a first-in, first-out (FIFO) principle, helpful for exploring search spaces.
Key Concepts
- -- Set
- A collection type in Python that contains unique values, allowing operations like union, intersection, and difference.
- -- Stack
- A data structure that allows adding and removing elements in a last-in, first-out order, commonly used for recursive processes.
- -- Queue
- A data structure that allows adding elements at one end and removing them from the other end, following a first-in, first-out order.
