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{...
The inOrder traversal is one of the most popular ways to traverse a binary tree data structure in Java. TheinOrdertraversal is one of the three most popular ways to traverse a binary tree data structure, the other two being thepreOrderandpostOrder. During the in-order traversal algorithm, ...

To convert a binary search tree into a doubly-linked list in sorted order, perform reverseinorder traversalon the BST. In the reverse inorder traversal, the right child for a node is processed before its left child. We insert the node at the front of the doubly linked list for each enco...
