Suppose we have a table: Doctor (DOCNO INT, DocName INT, Specialization VARCHAR(10), Salary Float) and it has an extendible hashing index. The hash function h (k) uses two rightmost bits of binary value of the number k and global depth of the directory structure is 2. The bucket size is four records ie it can store upto 4 records. Insert the elements 13, 22, 4, 2, 19, 6, 14, 16, 26, 28, 8, 7, 23,24 using extendible hashing technique.

Hash Table

A hash table also called a hash map, is a data structure that maps key-value pairs. The hash table can be used in complex systems to provide fast access and compact storage. A hash table is a structure that stores data in an abstract data type kind of associative array. It keeps data in an array format, with a distinct index value for every data value. If the index of the required data is known, then the data can be accessed very easily.
