The algorithm starts at the root node (selecting some arbitrary node as the root node in the case of a graph) and explores as far as possible along each branch before backtracking. Extra memory, usually a stack, is needed to keep track of the nodes discovered so far along a specified branch …

WebIn the DFS traversal of a binary tree, we access nodes in three different orders: preorder, postorder, and inorder. However, there is another traversal method that can access nodes in level-by-level order. This method is called level order traversal or breadth-first search traversal. In short, we refer to it as BFS traversal. how a prime minister is chosen
