Quadratic Probing Deep Dive: Collision Resolution With Real Examples | Data Structure

Video Description

Learn Quadratic Probing in Closed Hashing through clear explanations and simple examples. This lecture covers how quadratic probing resolves collisions using the i² sequence, how it differs from linear probing, and why certain slots may never be visited when the table size is non-prime. We walk through real examples, pseudocode, and probe sequences to show how insertion can fail even when empty slots exist. You will also understand the impact of load factor, especially why quadratic probing becomes unreliable when the load factor exceeds 0.5. In this lecture, you will learn: • What quadratic probing is and how it works • Step-by-step examples with visited and non-visited slots • Complete pseudocode for insert, search, and delete • Advantages and disadvantages of quadratic probing • Best, average, and worst-case time complexities • How quadratic probing reduces clustering compared to linear probing • Why prime table sizes and lower load factors are important • How quadratic probing differs from linear probing in behavior and performance ✨ Perfect for: Students learning Data Structures & Algorithms (DSA), preparing for interviews, or revising hashing concepts for exams.
