Message Route Video Solution | CSES Problemset | Graph Algorithms (BFS)

Описание: In this video, we solve the Message Route problem from the Graph Algorithms section of the CSES Problemset.

Message Route is a classic shortest path in an unweighted graph problem that helps you understand:
Breadth First Search (BFS)
Shortest path in graphs
Parent tracking & path reconstruction
How to approach graph problems in coding interviews

This problem is frequently asked in coding rounds, DSA interviews, and competitive programming contests, making it a must-practice problem for students.

💡 What you’ll learn in this video:
How to represent a graph using an adjacency list
Why BFS is optimal for shortest path in unweighted graphs
How to track parents to reconstruct the path
How to handle cases where no path exists
Writing clean and interview-ready graph code
