Our first method for organized graph traversal is called depth-first search (DFS). Whenever a vertex \(v\) is visited during the search, DFS will recursively visit all of \(v\) ‘s unvisited neighbors. Equivalently, DFS will add all edges leading out of \(v\) to a stack. The next vertex to be visited is determined by …

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. WebMar 26, 2024 · DFS Algorithm. Step 1: Insert the root node or starting node of a tree or a graph in the stack. Step 2: Pop the top item from the stack and add it to the visited list. Step 3: Find all the adjacent nodes of the node marked visited and add the ones that are not yet visited, to the stack. Step 4: Repeat steps 2 and 3 until the stack is empty.

WebDepth-First Search (DFS) is a graph traversal algorithm that explores the vertices of a graph in depth before backtracking. It can be used to traverse both directed and undirected graphs and can be implemented using recursion or an explicit stack data structure.
