Strongly Connected Components | Kosaraju & Tarjan in C++#C++ #Algorithms #DataStructures

In this video, we explain the Minimum Spanning Tree (MST) concept in graph theory and show how to build the most efficient network using the least total cost. You’ll learn what a spanning tree is, why cycles are not allowed, and how Kruskal’s Algorithm and Prim’s Algorithm solve real-world optimization problems.

This lecture is part of Data Structures & Algorithms in C++ and is useful for students, beginners, and coding interview preparation.
