Data structures for use in algorithms and other data manipulation.

import { BinarySearchTree } from "https://deno.land/std@0.224.0/data_structures/mod.ts";

const values = [3, 10, 13, 4, 6, 7, 1, 14];
const tree = new BinarySearchTree<number>();
values.forEach((value) => tree.insert(value));

[...tree]; // [ 1, 3, 4, 6, 7, 10, 13, 14 ]
tree.min(); // 1
tree.max(); // 14
tree.find(42); // null
tree.find(7); // 7
tree.remove(42); // false
tree.remove(7); // true
[...tree]; // [ 1, 3, 4, 6, 10, 13, 14 ]

Classes

A priority queue implemented with a binary heap. The heap is in descending order by default, using JavaScript's built-in comparison operators to sort the values.

An unbalanced binary search tree. The values are in ascending order by default, using JavaScript's built-in comparison operators to sort the values.

A red-black tree. This is a kind of self-balancing binary search tree. The values are in ascending order by default, using JavaScript's built-in comparison operators to sort the values.

Functions

Compares its two arguments for ascending order using JavaScript's built in comparison operators.
