Hashing is a method of directly computing the address of the record with the help of a key by using a suitable mathematical function called the hash function.

What it represent ?

Back

A hash table is an array-based structure used to store pairs.(key and Value)

Guess the concept?

Back

A 'hash bucket' refers to a storage unit within a hash table where data elements are stored after being hashed using a hash function.

Front

What is this?

Back

The hash function may return the same hash value for two or more keys. When two or more keys have the same hash value, a collision happens

Open addressing

Linear probing

Quadratic probing

Double hashing

Separate chaining (or linked list)

Bucket hashing (Closed Addressing)

Front

Guess the concept ?

Back

Overflow occurs when the hash table is full or when the probing sequence cannot find an empty slot due to clustering or other issues.

Front

Guess the method?

Back

One simple choice for a hash function is to use the modulus division indicated as MOD (the operator % in C/C++).

Back

A skip list is a data structure that allows fast search, insertion, and deletion operations by maintaining multiple levels of linked lists, with each level skipping over a certain number of elements.

Front

What is this ?

Back

Double hashing uses a second hash function to calculate the step size for probing, reducing clustering and improving collision resolution.

Rehashing is the process of resizing a hash table and recomputing the hash values for all keys to maintain efficiency when the load factor becomes too high.
