WebMar 12, 2011 · Using Stack, here are the steps to follow: Push the first vertex on the stack then, If possible, visit an adjacent unvisited vertex, mark it, and push it on the stack. If you can’t follow step 1, then, if possible, pop a vertex off the stack. If you can’t follow step 1 or step 2, you’re done. 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.
