BFS Graph Algorithm(With code in C, C++, Java and Python)

WebBreadth-first search (BFS) is an algorithm used for tree traversal on graphs or tree data structures. BFS can be easily implemented using recursion and data structures like dictionaries and lists. The Algorithm. Pick any node, visit the adjacent unvisited vertex, mark it as visited, display it, and insert it in a queue.
