What are some common use cases for hash maps?
Hash maps are often used for fast data retrieval, such as in caching, indexing, and implementing associative arrays.
Can you give me an example of how hash maps are used in caching?
Sure! In caching, hash maps store key-value pairs where the key is the data request and the value is the cached data, allowing quick access.
What about in databases?
In databases, hash maps can be used for indexing, enabling quick lookups of records based on unique keys.
Are there any downsides to using hash maps?
Yes, hash maps can consume more memory and may have performance issues with many collisions, which can slow down access.
