Data Structures | Python - Hash Table Insertion Operation | Data Structure

In this video, we explore hash table operations—specifically focusing on insertion. The tutorial explains the process of inserting a key-value pair into a hash table, which begins by applying a hash function to the key. The resulting index is then checked to see if the slot is empty. If it is, the key-value pair is inserted; if not, a collision occurs, and collision resolution techniques must be employed. These techniques include chaining (where colliding key-value pairs are stored in linked lists) and open addressing (which involves methods like linear probing and quadratic probing). The video provides step-by-step examples, showing how hash codes are calculated, indices are determined, and collisions are handled. Viewers also learn how to insert key-value pairs into the hash table, whether the slot is empty or occupied.
