WebMar 19, 2024 · A node in a non-binary tree can have more children. Traversing a tree means going through every node in it. The two most common ways to traverse a tree are breadth-first and depth-first. Breadth-first traversal means that we start from the top node, then go one level down, go through all of the children nodes from left to right. WebApr 7, 2024 · Path Finding We can either use Breadth First or Depth First Traversal to find if there is a path between two vertices. Finding all nodes within one connected component: We can either use Breadth First or Depth First Traversal to find all nodes reachable from a given node. AI: In AI, BFS is used in traversing a game tree to find the best move.

WebIn this traversal method, the root node is visited last, hence the name. First we traverse the left subtree, then the right subtree and finally the root node. In the below python program, we use the Node class to create place holders for the root node as well as the left and right nodes. Then we create a insert function to add data to the tree.
