Question: Let's turn to an article that intuitively introduces various types of B trees. B tree That is, the binary search tree: 1. All non-leaf nodes have at most two sons (left and right ); 2. All nodes store a keyword; 3. The left pointer of a non-leaf node points to the subtree smaller than its keyword, And the right Pointer Points to the subtree larger than its keyword; For example: B-

Disclaimer: This article only introduces the definition of these trees and the comparison between them. Does not involve their insertion, deletion, splitting, integration and other operations. These will be described in a later article.B-TreeBinary search tree: 1.所有非叶子结点至多拥有两儿子（Left和Right）； 2.所有结点存储一个关键字； 3.非叶子结点的左指针指向小于其关键字的子树，右指针指向大于其关键字的子树；Such as:BTree search, starting from the root node, if the query keyword is equal to the keyword of the n

What are B, B-, B +, and B * trees? B tree That is, the binary search tree: 1. All non-leaf nodes have at most two sons (left and right ); 2. All nodes store a keyword; 3. The left pointer of a non-leaf node points to the subtree smaller than its keyword, And the right Pointer Points to the subtree larger than its keyword; For example: B-tree search starts f

Title Link: BZOJ-3196Problem analysisThe interval kth and interval rank are implemented by the tree array nested segment tree, and the interval precursor successor is implemented by the set of segment tree sets.In order to save space, need to go offline, first discretization, so that the size of the required array can be smaller, you can pass 128MB =Well, that's

Title Link: BZOJ-1901Problem analysisThis problem can be solved by tree array or line segment tree.The first layer is the interval and the second layer is the weight value.Both spatial complexity and time complexity are O (n log n).CodeTree array nested segment tree#include [Bzoj 1901] Dynamic rankings "Tree array set segment

Title one: Print binary tree from top down Each node of the two-fork tree is printed from top to bottom, and the same-level node prints from left to right. The topic Analysis: This problem actually examines the tree traversal algorithm, the traversal usually has the preface, the middle order, the post-order traversal, this question examines the level traversal. 1

For a normal two-fork search tree, after multiple insertions or deletions, it is easy to get the tree out of balance, resulting in a tree whose depth is not O (Logn), but close to O (N), which greatly reduces the search efficiency of the tree. One solution is to have an additional structural condition called Balance: t

Binary sort tree, also known as B-Tree, is a data structure commonly mentioned in the search algorithm, this paper introduces its basic concept and search process, analyzes its search efficiency, and then leads to the concept of balance tree (AVL tree). structure of the B-tree
