WitrynaC++ implementation of extendible hashing. Contribute to nitish6174/extendible-hashing development by creating an account on GitHub. 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.
