The result of a depth-first search of a graph can be conveniently described in terms of a spanning tree of the vertices reached during the search. Based on this spanning tree, the edges of the original graph can be divided into three classes: forward edges, which point from a node of the tree to one of its descendants, back edges, which point from a node to one of its ancestors, and cross edges… 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.

There are two search algorithms exist for binary tree: breadth-first search (BFS) and depth-first search (DFS). BFS search nodes level by level, starting from the root node.

WebBased on the order of visiting the nodes, DFS traversal on a binary tree can be divided into the following three types: Inorder traversal, preorder traversal, and postorder traversal. 1. Inorder Traversal Recursively traverse the left subtree of the current node. Access the data of the current node.
WebJun 15, 2024 · Maximum Width of a Binary Tree at depth (or height) h can be 2 h where h starts from 0. So the maximum number of nodes can be at the last level.
