Which data structure is most suitable for implementing an LRU (Least Recently Used) cache?

An LRU (Least Recently Used) cache is most efficiently implemented using a combination of a HashMap and a Doubly Linked List. The HashMap provides O(1) access to cache entries, while the Doubly Linked List maintains the order of usage, allowing for quick updates to the most recently and least recently used elements.

Why is the space complexity of a recursive algorithm often higher than its iterative counterpart?

The space complexity of a recursive algorithm is often higher than its iterative counterpart because recursion requires additional stack space to store the state of each function call. Each recursive call adds a new frame to the call stack, which increases the overall space complexity.

Where is a heap data structure typically used?

A heap data structure is typically used to implement a priority queue. Heaps allow for efficient retrieval of the highest (or lowest) priority element and support operations like insertion and deletion in logarithmic time, making them ideal for priority queues.
