Does BFS also work with disconnected graphs? The conventional/straightforward BFS approach does not work with the disconnected graphs as not all the vertices are connected with all the other vertices. But, with a modification in the simple approach, you can make BFS work for disconnected graphs too. What is the time complexity of the BFS algorithm? The time complexity of the BFS algorithm is the same…

In the previous post, BFS only with a particular vertex is performed i.e. it is assumed that all vertices are reachable from the starting vertex. …

Breadth First Search (BFS) algorithm traverses a graph in a breadthward motion and uses a queue to remember to get the next vertex to start a search, when a dead end occurs in any iteration. he only catch here is, that, unlike trees, graphs may contain cycles, so we may…
