WebWhereas BFS keeps track of vertices on a queue, DFS uses a stack. We can either use our own stack, or take advantage of the run-time stack and write DFS recursively. If we use our own stack the code above almost works for DFS, with the stack replaced by a queue, enqueue replaced by push, and dequeue replaced by pop. We do have to be careful ...

WebIt all depends on how deep and wide the tree is as well as where the solutions are located. Suppose the problem is 'find the fastest route from Berlin to Paris'. If you use DFS, you have to explore each direction to the fullest. You might end up in Hong Kong before you even see France. That is obviously not efficient. 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 ...
