Hash tables employ hashing functions to store and retrieve data from "summary" of Data Structures and Algorithms in Python by Michael T. Goodrich,Roberto Tamassia,Michael H. Goldwasser
Hash tables, a fundamental data structure in computer science, utilize hashing functions to efficiently store and retrieve data. The primary purpose of a hash table is to map keys to values, allowing for quick access to stored information. The process begins with the application of a hashing function to the key, which generates a unique hash code corresponding to a specific location within the table. By utilizing hashing functions, hash tables can achieve constant-time complexity for both insertion and retrieval operations in the best-case scenario. This is made possible by the direct mapping of keys to their respective hash codes, enabling immediate access to the corresponding...
