Binary tree preorder traversal iterative
Did you know?
WebDepth-first traversal (dotted path) of a binary tree: Pre-order (node visited at position red ): F, B, A, D, C, E, G, I, H; In-order (node visited at position green ): A, B, C, D, E, F, G, H, I; Post-order (node visited at position blue ): A, C, E, D, B, H, I, G, F. WebThe problem statement asks us to print the preorder traversal of the given binary tree using the iterative method. Generally, we use the recursive method because that is easier. But …

WebThe traversal can be done iteratively where the deferred nodes are stored in the stack, or it can be done by recursion, where the deferred nodes are stored implicitly in the call stack. For traversing a (non-empty) binary tree in a postorder fashion, we must do these three things for every node nstarting from the tree’s root:
