Inorder Traversal | Problem Description Given a binary tree, return the inorder traversal of its nodes values. NOTE: Using recursion is not allowed. Problem Constraints 1 <= number of nodes <= 105 Input Format First and only argument is root node of the

The easiest way to implement theinOrdertraversal algorithm in Java or any programming language is by using recursion. Since the binary tree is a recursive data structure, recursion is the natural choice for solving a tree-based problem. TheinOrder()method in theBinaryTreeclass implements the logi...
1. 中序遍历(In-order Traversal):先访问左子树,然后是根节点,最后访问右子树。这种遍历方式可以按照“左-根-右”的顺序访问所有节点。 2. 前序遍历(Pre-order Traversal):先访问根节点,然后是左子树,最后访问右子树。这种遍历方式可以按照“根-左-右”的顺序访问所有节点。 3. 后序遍历(Post-order Traversal...

In this article, we are going to find what inorder traversal of a Binary Tree is and how to implement inorder traversal iteratively without using recursion? We have provided the implementation in C++. Submitted by Radib Kar, on July 30, 2020 ...
inOrderTraversal(node.right); } } We are using recursion for these examples, you can also implement the same traversal using while loop. 2.3. Postorder Binary Tree Traversal The post-order binary tree traversal, we traverse the left sub tree, the right sub-tree and finally visit the root ...

In this article, we covered about Binary tree InOrder traversal and its implementation. We have done traversal using two approaches: Iterative and Recursive. We also discussed about time and space complexity for the traversal. Java Binary tree tutorial Binary tree in java Binary tree preorder trav...
