WebThe worst time complexity in linear search is O(n), and O(logn) in binary search. In both the searching techniques, the searching depends upon the number of elements but we want the technique that takes a constant time. So, hashing technique came that provides a constant time. In Hashing technique, the hash table and hash function are used. WebDynamic hashing is typically implemented using a technique called extendible hashing. This is a method where the hash table is initially created with a small number of slots. As more elements are added to the …
