#Data Structures

Engage in a deep discussion on CS fundamentals, focusing on data structures and problem-solving implementation, particularly on data structure and graph algorithms.

Solve DSA problems that utilize the sliding window technique and binary search. Focus on implementing algorithms using these strategies.

Implement an LRU Cache using an Array, Queue, Doubly Linked List, and HashMap. Describe the operation of each component in your solution.

If a CEO has two direct reports, and each of those reports has exactly two people reporting to them, which data structure best represents this hierarchy? Specify the reasons for your choice.

Implement a caching system and explain the underlying data structures that you would use. Discuss the trade-offs of your chosen approach.
