Master Dijkstra’s Algorithm | Find the Shortest Path Efficiently | Java | DSA | Min Heap Method

In this detailed yet beginner-friendly tutorial, we unlock the power of graphs with Dijkstra's Algorithm, an essential technique for finding the shortest path from a source node to all other nodes in a graph. Whether you're preparing for coding interviews or solving real-world routing problems, this video has you covered!

✅ What you’ll learn:
The intuition behind Dijkstra’s algorithm
Step-by-step dry run on a weighted graph
Priority Queue (Min-Heap) based implementation
Complete Java implementation using PriorityQueue

This algorithm runs in O((V + E) log V) time using a min-heap, making it highly efficient for dense graphs with non-negative weights.
