B-tree implementation in C. Contribute to tidwall/btree.c development by creating an account on GitHub.
1. 写在前面 说起B+树,大家应该都很熟悉。B+树是一种平衡的多路搜索树,广泛在操作系统和数据库系统用作索引。相比于内存的存取速度,磁盘I/O存取的开销要高上几个数量级。而将B+树用作索引时,它可以在查找过程有效地减少磁盘I/O操作次数。 一般涉及B+Tree的书籍和文章都会提到它广泛用作外存的索引中,但是...

4.2 线索化过程的实现(Implementation of Threading Process) 线索化是将二叉树转换为线索二叉树的过程。我们可以通过中序遍历来实现这个过程。 void threadBinaryTree(ThreadedTreeNode* root) { if (root == nullptr) return; static ThreadedTreeNode* prev = nullptr; threadBinaryTree(root->left); if (prev ...

btree.c- This file contains the implementation of the B-Tree storage engine used by SQLite. The interface to the rest of the system is defined by "btree.h". The "btreeInt.h" header defines objects used internally by btree.c and not published to the rest of the system. ...
This is implementation of Bayer Trees, sometime referred to as Balanced Tree and normally used for indices of data bases. These routines provide all stuff that is needed to create and destroy; insert, update and delete; load and destroy; search and traverse; check a tree.Sort huge amounts ...
