kandi X-RAY | avl_tree Summary

avl_tree is a C library typically used in Artificial Intelligence, Dataset applications. avl_tree has no bugs, it has no vulnerabilities and it has low support. However avl_tree has a Non-SPDX License. You can download it from GitHub.

This is a zero-dependency, high performance C implementation of AVL trees. It is intended to be incorporated into C programming projects that need to use self-balancing binary search trees. This implementation is "intrusive", meaning that the tree node structure must be embedded inside the data structure to be indexed in the tree. This is the style commonly used in kernel data structures. This is actually the more general style of implementation; a void pointer and comparison callback-based implementation can (but does not have to be) be built on top of it. This implementation is non-recursive, so it does not suffer from stack overflows.

QUESTION

Implementation of std::set using different data structures

Asked 2019-Sep-23 at 09:14

Inspired by this question: Why isn't std::set just called std::binary_tree? I came up with one of my own. Is red-black tree the only possible data structure fullfilling requirements of std::set or are there any others? For instance, another self-balancing tree - AVL tree - seems to be good alternative with very similar properties. Is it theoretically possible to replace underlying data structure of std::set or is there a group of requirements that makes red-black tree the only viable choice?

AVL trees have worse performance (not to be confused with asymptotic complexity) than RB trees in most real world situations. You can base std::set on AVL trees and be fully standard-compliant, but it will not win you any customers.

QUESTION

How to test a custom implementation of an AVL tree

Asked 2019-Aug-10 at 15:50

I've implemented an AVL tree in C++ and would like to stress test it. To do that I need some other implementation of a AVL tree to compare the results.

As an acceptance criterion, I'm going to use preorder and postorder traversals. If they are matching appropriately with my results, it will mean that the algorithms are working correctly.

But the problem is that I couldn't found any C++ library containing an implementation of an AVL tree that provides a preorder and postorder traversal functionality. How else is it possible to stress test it?

An AVL tree maintains certain invariants. You just need to check it after every insertion or deletion, and don't waste your time trying to incorporate another implementation of an AVL tree into your project.

Ok, it's been 14 years since I touched Pascal last time :)

So the problem is indeed with rotate_l function. You are passing a parameter by-reference as indicated by var keyword.
