📘 Welcome to Part 158 of Code & Debug’s DSA Python Course!
In this video, we dive into one of the most powerful data structures for graph problems – Disjoint Set Union (DSU), also known as Union-Find.
Disjoint Set is widely used in problems related to connected components, cycle detection, and Minimum Spanning Trees (Kruskal’s Algorithm).
👨🏫 Here’s what we cover in this video:
✅ What is a Disjoint Set and where it’s used
✅ find() function with Path Compression for optimization
✅ union() with Union by Size strategy
✅ Full code walkthrough and working demo
✅ Time Complexity explanation – almost O(1) due to inverse Ackermann function
✅ Real-world examples of usage
This foundational concept appears in many advanced graph problems, and mastering it is crucial for acing competitive programming and interviews.
