【Data Structure - Hash Tables Vol.2】Hash Function

In this video, we dive into the concept of hash functions, a core foundation of hash tables. You’ll learn how a hash function converts any input into a fixed-length value, and explore its key properties: one-wayness, determinism, and sensitivity to small changes. We’ll also see how hash functions are applied in hash tables to enable O(1) fast data access, and compare this with arrays to understand why hash tables are so efficient. Additionally, we touch on real-world examples like MD5 and SHA-256, highlighting the difference between their use in cryptography and in data structures. ⭐️ This video is a silent tutorial designed for self-paced learning.
