Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a custom data structure that functions as both a stack and a queue. Provide methods for all stack and queue operations, ensuring it retains the properties of both.

💡 Hint: Consider how the two data structure concepts might interact or overlap.

Challenge 2 Hard

Implement a class that behaves like a circular queue. Discuss how you manage the front and rear indices to achieve this structure.

💡 Hint: Think about how to effectively reuse space in a fixed-size array.
