Before you attempt this problem, you might want to try coding a pre-order traversal iterative solution first, because it is easier. On the other hand, coding a post-order iterative version is a challenge. See my post:Binary Tree Post-Order Traversal Iterative Solutionfor more details and an ...
iterative approach: /** * Definition for binary tree * struct TreeNode { * int val; * TreeNode *left; * TreeNode *right; * TreeNode(int x) : val(x), left(NULL), right(NULL) {} * }; */ #include <stack> using namespace std; class Solution { public: vector<int> inorderTrav...

As I have told you before, during the in-order traversal value of the left subtree is printed first, followed by root and right subtree. If you are interested in the iterative algorithm, you can further check thistutorialof implementing in order traversal without recursion. ...
Here is our complete Java program to implement iterative inorder traversal in Java. Similar to the iterative PreOrder algorithm we have used the Stack data structure to convert the recursive algorithm to an iterative one, one of the important things every programmer should remember. We have used...
Iterative We can use a stack toemulate the recursion. We first push the left nodes as many as possible, if not, we push the right sub trees. This gives an inorder traversal. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 ...
