There's nothing at the previously calculated index, the Hash Table is a data structure to map key to values (also called Table or Map Abstract Data Type/ADT). 📚 HashMap and HashSet Implementation in Python This repository contains an implementation of a HashMap and HashSet in Python, utilizing separate chaining for collision resolution. The first hash function is used to compute the initial hash value, and the second hash function is used to compute the step size for the probing sequence. A parallel chain consists of multiple sub-chains, which have their own input and output. For the separate chaining hash table, the length of any of those individual lists is hoped to be a small fraction of the total number of elements, n. Despite the confusing naming convention, open hashing involves storing collisions outside the table, while closed hashing stores one of the records in another slot within the table. When prioritizing deterministic performance over memory efficiency, two-way chaining is also a good choice. It uses the concept of Open Addressing (linear probing) to find first empty place for colliding element from the bottom of the hash table and the concept of Separate Chaining to link the colliding elements to each other through pointers.
