What is Hashing in Data Structure?
Hashing is a technique used in data structures to store and retrieve data efficiently. It involves using a hash function to map data items to a fixed-size array which is called a hash table.
How it works:
- Hash Function: You provide your data items into the hash function.
- Hash Code: The hash function crunches the data and give a unique hash code.
- Hash Table: The hash code then points you to a specific location within the hash table.
Hashing in Data Structure
Hashing is a fundamental data structure that efficiently stores and retrieves data in a way that allows for quick access. It involves mapping data to a specific index in a hash table using a hash function that enables fast retrieval of information based on its key. This method is commonly used in databases, caching systems, and various programming applications to optimize search and retrieval operations.
