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. WebStep 1 - Define a Stack of size total number of vertices in the graph. Step 2 - Select any vertex as starting point for traversal. Visit that vertex and push it on to the Stack. Step 3 - Visit any one of the non-visited adjacent vertices of a vertex which is at the top of stack and push it on to the stack. Step 4 - Repeat step 3 until there is ... cigna valley health
