Hashing in DSA

Hashing is a crucial technique in data structures and algorithms (DSA) that provides efficient ways to store, retrieve, and manage data. It is widely used in competitive programming to solve problems involving searching, duplicates, and efficient data access, thanks to constant-time complexity in ideal cases.

📄️ Insertion in Hash Table

Insertion involves adding a key-value pair to the hash table. If the key already exists, it may update the existing value.

📄️ What is Hashing and Hash Maps?

Hashing is a technique used to uniquely identify a specific object from a group of similar objects. Hash maps are data structures that implement this technique.

📄️ Deletion in Hash Table

Deletion involves removing a key-value pair from the hash table using the key.

📄️ Importance of Hashing

Hashing is an essential technique in data structures and algorithms used to optimize data retrieval, storage, and management through efficient key-value mapping.

📄️ Search in Hash Table

Search involves retrieving the value associated with a given key in the hash table.

📄️ What is a HashSet?

A HashSet is a data structure used to store unique elements and provides efficient insertion, deletion, and search operations.

📄️ Update in Hash Table

Update involves modifying the value associated with an existing key in the hash table.
