Breadth-First Search
Iterative Implementation using Queue
BFS is a traversing algorithm where you should start traversing from a selected node (source or starting node) and traverse the graph layer-wise thus exploring the neighbor nodes (nodes that are directly connected to the source node). You must then move towards the next-level neighbor nodes.
Time Complexity: O(V+E)
Space Complexity: O(V)
Where V represents vertices and E represent edges
This issue has been automatically marked as inactive because it has not had recent activity. It will be closed in 15 days if no further activity occurs. Thank you for your contributions.
