C++ binary algorithm: random numbers in blacklist
Involving knowledge points binary search Title Given an integer n and a non-duplicate blacklist integer array blacklist . Design an algorithm to select an integer that is not included in the blacklist from any integer in the range [0, n – 1]. Any integer in the above range that is not in the blacklist should […]

Preorder, inorder, postorder, and level order traversal of binary trees
Reference content: Five minutes will give you a thorough understanding of non-recursive traversal of binary trees Python implements non-recursive traversal of binary trees Binary tree traversal – depth first (front, middle and last order) + breadth first (level order traversal) Construct a binary tree Define the binary tree structure as follows struct node {<!– –> […]

Binary search tree (BinarySearchTree/BSTree), also called binary sorting tree or binary search tree
1. Definition of binary search tree Binary search tree: a binary tree, which can be an empty tree; or meet the following conditions, at any node, 1. All key values of the non-empty left subtree are less than the key values of its root node; 2. All key values of the non-empty right subtree are […]
Tree Topic – Binary Search Tree and Inorder Traversal
Hello everyone, my name is Fangyuan. I plan to write a special topic on trees, including binary search trees, pre-order, in-order, post-order traversal and red-black trees. I also want to try to see if I can write red-black trees well. This article is about binary search trees, which is also the basis for all subsequent […]
