Hash Tables: Theory, Implementation, and Universal Hashing
Update: 2025-02-16
Description
In this episode, we explore hash tables, a data structure designed for efficient insertion, deletion, and searching of data using keys. The document contrasts direct addressing with hashing, highlighting the space efficiency of hash tables when dealing with large key universes. It discusses collision resolution techniques like chaining and open addressing, exploring the trade-offs between them. Different hashing methods, including division and multiplication, are analyzed for their suitability in diverse contexts. We also introduce more advanced concepts like universal and adaptive hashing to optimize performance and handle dynamic data sets.
