WebAug 3, 2024 · In pre-order traversal of a binary tree, we first traverse the root, then the left subtree and then finally the right subtree. We do this recursively to benefit from the fact that left and right subtrees are also trees. Traverse the root. Call preorder () on the left subtree. Call preorder () on the right subtree. 2. WebDepth First Search ( DFS ) Algorithm. DFS is an algorithm for traversing a Graph or a Tree. DFS starts with the root node and explores all the nodes along the depth of the selected path before backtracking to explore the next path. DFS makes use of Stack for storing the visited nodes of the graph / tree. Example: Consider the below step-by-step ...

WebBy Zeeshan Alam. In this tutorial we will learn about the traversal (or search) of the graph by using the two approaches, one is the breadth-first search (BFS) and another one is depth-first search (DFS).
