Data Structures
Hash tables allow multiple values to be stored using a singlevariable name. A value can be accessed by its name instead of byits position in the array. Hash Tables are very useful when we wantto look up items from a list.
The problem of ahash table creation is examined. The Following are the basicprimary operations of a hash table.
Search − Searches an element in ahash table.
Insert − inserts an element in ahash table.
delete − Deletes an element from ahash table.
The program (IN PERL) must work with menu (i:insert, r: remove ,d: display the hash table , q: for quit). The user must insert thewords after having picking up the i (insert).
A hash function converts keys into array indices. The hashfunction can calculate the number of the basket. Find first, thetotal of ASCI values of all the letters and second finds theremainder using the number of buckets (find the module). Create ahash table for a number of baskets. The number of buckets (or the Marray indices) is equal to ten.
The second component of a hashing algorithm is collisionresolution: a strategy for handling the case when two or more keysto be inserted hash to the same index. A straightforward approachto collision resolution is to build, for each of the M arrayindices, a list of the key-value pairs whose keys hash to thatindex.
To enable efficient search through a two-step process isperformed: hash to find the list that could contain the key, thensequentially search through that list for the key.
After the end of the insert, you have to display the data foreach basket. Finally you test the remove operation. The hash withchaining technique is needed.
For the implementation it is preferable to use package withsubroutines for the operations.
