Some of the most critical aspects of a hash table are: Access via key (calculates key by hash function) Mapped to data structures (the storage structure of the hash table itself) Processing of mappings (conflict or collision

In the previous series, we introduced sequential lookups based on unordered lists, binary lookups based on ordered arrays, balanced lookup trees, and red-black trees, which are their time complexity on average and worst-case scenarios:It can be seen
