    Teaching Demo Description

    Data come in various forms and sizes. A common scenario that computer science problems need to address is how to efficiently store the data for quick retrieval. Hashing is a fundamental technique that enables constant-time (O(1)) data retrieval while also provides enhanced security. In this lecture, we will discuss the significance of hashing, and introduce the basic concepts behind it including hash function and hash table. We will also briefly examine the problems that collisions introduce and the solutions.
