Mathematical Formula
Overview & Explanation
Breadth First Search traverses a graph level by level using a Queue data structure.
How It Works
- Enqueue starting node and mark visited.
- Dequeue node, process neighbors, and enqueue unvisited neighbors.
Practical Applications
- Shortest path in unweighted graphs
- Web crawlers
- Social network connections
BFS Traversal Example
Traversal from node A
Queue
Dequeue A
