WebWe can easily implement recursive binary tree traversals (preorder, inorder, and postorder) iteratively using a stack. We need to understand the flow of recursive calls in DFS traversal and mimic what the compiler does in the background. So, we need to follow a similar process and use our own stack to simulate the recursive binary tree traversal using … WebDepending on the order in which we do this, there can be three types of traversal. Inorder traversal First, visit all the nodes in the left subtree Then the root node Visit all the nodes in the right subtree inorder(root->left) …
