A minimal perfect hash function is a type of hash function that maps a set of n keys to a range of n consecutive integers with no collisions, ensuring optimal space efficiency. It is especially useful for static sets where the set of keys does not change, allowing for constant time lookups without wasted space.

A hash function is a mathematical algorithm that converts an input (or 'message') into a fixed-size string of bytes, typically a hash code. It is widely used in computer science for data indexing, retrieval, and encryption, ensuring data integrity and security.
