Minimal Perfect Hashing Lookup
Minimal Perfect Hashing Lookup Minimal perfect hashing is a static dictionary technique. It builds a hash function for a fixed set of $n$ keys so that every stored key maps to a unique integer in the range $0$ to $n - 1$. Unlike ordinary perfect hashing, a minimal perfect hash uses exactly one table slot per key. Lookup computes the hash position, checks the stored key, and returns the associated...
