Collision In Hash Table | Data Structure

In this video from Data structure video series, we dive into the concept of hash tables, focusing on how data is stored using key-value pairs through a hash function. We explore how hash codes are generated, how indices are calculated, and what happens when collisions occur—when two keys map to the same index.

The video explains two popular collision resolution techniques: Chaining, where multiple values are linked at the same index using structures like linked lists, and Open Addressing, which searches for the next available slot using probing techniques like linear and quadratic probing.

By the end of the tutorial, you'll understand how collisions are handled and the differences between these two resolution methods. Perfect for beginners learning about hash tables and data structures!
