Tree_collections

The purpose of this library is to provide APIs that allows users to create memory efficient binary search tree, red-black tree and AVL tree. Besides, by using this library, users can investigate the performance difference between red-black tree and avl tree, which helps them deeply understand the algorithms.

Quick Start

use tree_collections::prelude::*;

let mut rb_tree = RBTree::new();
rb_tree.insert(1);
rb_tree.insert(2);
rb_tree.insert(3);
rb_tree.insert(4);
rb_tree.insert(5);
rb_tree.delete(3);
println!("Red-Black Tree:");
rb_tree.print();
println!("Number of leaves: {:?}", rb_tree.count_leaves());
println!("Height of tree: {:?}", rb_tree.height());

let mut avl_tree = AVLTree::new();
avl_tree.insert(1);
avl_tree.insert(2);
avl_tree.insert(3);
avl_tree.insert(4);
avl_tree.insert(5);
avl_tree.delete(3);
println!("AVL Tree:");
avl_tree.print();
println!("Number of leaves: {:?}", rb_tree.count_leaves());
println!("Height of tree: {:?}", rb_tree.height());
