Hash Tables | Data Structure

In this video from Data Structures series, we explore hash tables — a powerful data structure that stores data in key-value pairs for fast and efficient retrieval.

You'll learn how hash tables work, including the concept of hashing, how hash functions convert keys into numerical indices, and how these indices determine where data is stored in the table.

We'll also cover real-life analogies, how collisions occur, and briefly introduce methods like chaining and open addressing to handle them. This tutorial sets the foundation for understanding hash table operations, which will be discussed in the next lesson.
