2. Iteratively method using stack. Use a while loop, the condition of the loop is that either the current node is not null or the stack is not empty. If current node is not null, push it into the stack. If the node is null, this means we've gone to the leftmost of the remaining...
Preorder traversal starts printing from the root node and then goes into the left and right subtrees, respectively, while postorder traversal visits the root node in the end. #include<iostream>#include<vector>using std::cout;using std::endl;using std::string;using std::vector;structTreeNode{...
