Open Addressing (Quadratic Probing): Similar to linear probing, but probes quadratically (index + 1², index + 2², index + 3², ) to potentially reduce clustering. Python Implementation of Hash Table - resizable hash table with quadratic probing A Hash Table is a data structure that uses a hash function to efficiently map keys to values (Table or Map ADT), for efficient search/retrieval, insertion, and/or removals. In general, a hash table consists of two major components, a bucket array and a hash function, where a bucket array is used to store the data (key-value entries) according to their computed indices and a hash function h maps keys of a given type to integers in a fixed interval [0, N -1]. Quadratic probing helps distribute keys more evenly throughout the hash table, reducing the likelihood of clustering. The great thing about hashing is, we can achieve all three operations (search, insert and delete) in O (1) time on average. com/msambol/dsa/blob/master/data_structures/hash_table. , 1 ², 2 ²,3 ²).
