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{...
Given an array of numbers, verify whether it is the correct preorder traversal sequence of a binary search tree. You may assume each number in the sequence is unique. Follow up: Could you do it using only constant space complexity?
inorder traversal of a binary tree in Java, in thefirst part, I have shown you how to solve this problem using recursion and in this part, we'll implement the inorder traversal algorithm without recursion. Now, some of you might argue, why use iteration if the recursive solution is so ...
