1, or 2 offspring nodes. Every single node in abinary treehas a value of its own and two pointers to its children, one pointer for the left child and the other for the right child.

Traversing a binary tree refers to visiting and processing each node in the tree in a specific order. There are three common methods for traversing binary trees: Inorder Traversal: In an inorder traversal, the nodes are visited in the order: left subtree, current node, right subtree. This ...

4.3 遍历线索二叉树(Traversal of Threaded Binary Tree) 遍历线索二叉树的过程与遍历普通二叉树类似,但需要注意的是,我们需要根据线索来判断是否需要访问前驱或后继节点。 void inorderTraversal(ThreadedTreeNode* root) {ThreadedTreeNode* curr = root;while (curr != nullptr) {while (curr->leftThreaded == ...
A binary search tree is a binary tree where for every node, any descendant ofNode.lefthas a value strictly less thanNode.val, and any descendant ofNode.righthas a value strictly greater thanNode.val. A preorder traversal of a binary tree displays the value of the node first, then travers...
