What are the limitations of hash maps?

What are the limitations of hash maps?

Hash maps are efficient but have limitations like collision handling, memory usage, and order of elements.

Can you explain collision handling in hash maps?

Sure! Collision handling is necessary when two keys hash to the same index. Common methods include chaining and open addressing.

What happens if the load factor is too high?

If the load factor is too high, it can lead to increased collisions, which degrades performance and slows down operations.

Are there alternatives to hash maps?

Yes, alternatives include balanced trees, arrays, and linked lists, each with its own advantages and use cases.

When should I avoid using a hash map?

Avoid using hash maps when you need ordered data or when memory usage is a critical concern.
