How bfs works

WebI learned from my graph theory data structure classes that Breadth-first search is used in GPS and digital maps. I tried looking for the possible use of Algorithms (Breadth First … WebIn BFS, we initially set the distance and predecessor of each vertex to the special value ( null ). We start the search at the source and assign it a distance of 0. Then we visit all the neighbors of the source and give each neighbor a distance of 1 and set its predecessor to be the source. Then we visit all the neighbors of the vertices whose ...
