In this video, we explore the update operation in hash tables in a clear and beginner-friendly way. You’ll learn how to update the value of a key using different collision handling techniques such as basic hash tables without collision handling, the chaining method, and open addressing with linear and quadratic probing.
We walk through step-by-step instructions on how to find the index using the key, what to do if the slot is empty or filled, how to search for the key and update its value, and what message to return if the key is not found.
Real-life examples make it easy to understand how updating works in each method. This is a great video for students or anyone learning data structures and hash tables.
