A tree is a connected graph without cycles. A rooted tree has a special vertex called the root. A parent of a vertex v is the last different from v vertex on the path from the root to the vertex v. The depth of the vertex v is the length of the path from the root to the verte...
LeetCode之“树”:Validate Binary Search Tree 题目链接 题目要求: Given a binary tree, determine if it is a valid binary search tree (BST). Assume a BST is defined as follows: The left subtree of a node contains only nodes with keys less than the node's key....
The following code illustrates how to use the BinaryTree class to generate a binary tree with the same data and structure as binary tree (a) shown in Figure 2.BinaryTree<int> btree = new BinaryTree<int>(); btree.Root = new BinaryTreeNode<int>(1); btree.Root.Left = new BinaryTree...
