Cuckoo sequence program
Problem Statment
Cuckoo sequence program or Cuckoo Hashing is a method used to solve the problem when a collision occurs in a Hash Table. Collisions are likely of two hash values of a hash function in a table. A collision occurs when two hash values for the same key occurs in the hash function of a table. To resolve that collision we use Cuckoo Hashing.
As from the name, Cuckoo Hashing is just derived from some characteristic of a cuckoo, as a chick of the cuckoo shove or pushes the other eggs or the young ones out of the nest to make a place for own. The same we do in Cuckoo Hashing, trying to insert a new key into the hash table we just push the older key to the new place. And that is how Cuckoo Hashing implemented.
Collision
When a new key, which we try to insert in a Hash Table find an already occupied place in a Hash Table. In that case, this situation is called a collision. When a new key indicates a place to be inserted which is already occupied in a Hash Table is called a collision.
This situation can be handled by using some of the Collision handling techniques.
- Closed Addressing or Separate Chaining
- Open Addressing
Closed Addressing or Separate Chaining
The Separated Chaining is one of the techniques to handle collision problems of Hash Tables. In Separate Chaining, the concept is to join a cell to a linked list to store records for the same hash function values.
Open Addressing
Open Addressing is also a method to resolve the problem of collision.
