What are some practical use cases for hash maps?
Hash maps are great for scenarios like caching, counting occurrences, and implementing associative arrays.
Can you give me an example of how to use a hash map for counting occurrences?

What about using hash maps in databases?
In databases, hash maps can be used for indexing, allowing for faster data retrieval by mapping keys to their corresponding records.
Are there any downsides to using hash maps?
