What is Hashing? Explain the procedure to obtain a hashing table.


Answered by Vikas Saxena on 2005-05-12 06:22:10: Hashing is a method to store data in an array so that storing, searching, inserting and deleting data is fast .For this every record needs an unique key.  
The basic idea is not to search for the correct position of a record with comparisons but to compute the position within the array. The function that returns the position is called the hash function and the array is called a hash table.
