WebJan 9, 2010 · Pick a large prime number H (that's greater than maximal number of children). To hash a tree, hash its root, pick a child number H mod n, where n is the number of children of root, and recursively hash the subtree of this child. This seems to be a bad option if trees differ only deeply near the leaves.

For example, If the size of a hash table is 10 and k = 112 then h (k) = 112 mod 10 = 2. The … WebDynamic Hashing. The ‘Dynamic Hashing’ technique allows the hash function to be modified dynamically to accommodate the growth or shrinkage of the database. The ‘dynamic hashing’ technique we use is called ‘Extendible Hashing’. This technique is used to know the address of the required record, whose key value is given.
