Witryna30 lip 2024 · C++ Program to Implement Hash Tables with Double Hashing C++ Server Side Programming Programming A hash table is a data structure which is used to store key-value pairs. Hash function is used by hash table to compute an index into an array in which an element will be inserted or searched. WitrynaThe computed value is taken modulo pow (2, exthash_t.level) (the size of the hash table). The hash table contains only a pointer to the bucket where elements are stored. The reason is that extendible hashing can be used to hash on external storage. In this implementation the table contains a pointer to the root node of a tree.
