Programming technique for resolving duplicate hash values in a hash table data structure
In computer science, dynamic perfect hashing is a programming technique for resolving collisions in a hash table data structure.[1][2][3]
While more memory-intensive than its hash table counterparts,[citation needed] this technique is useful for situations where fast queries, insertions, and deletions must be made on a large set of elements.
