BSF graph explanation
• BFS (Breadth-First Search) is a graph traversal algorithm that explores all the neighbor nodes at the present depth before moving on to the nodes at the next depth.

• It uses a queue data structure to keep track of the nodes to visit next.

• BFS is often used to find the shortest path in an unweighted graph.

• Example: BFS can be used to find the shortest path in a maze from the starting point to the exit.
