feat: Use extractComparable in the BST data structure to control key comparisons instead of directly passing a comparator. Use isReverse to control whether the tree is reversed instead of relying on the comparator. Removed the unnecessary getNodeByKey method.chore: Support list configuration for performance testing.

|
||
> ***Our goal is to make every data structure as convenient and efficient as JavaScript's Array.***
|
||
|
||
## Installation and Usage
|
||
|
||
### npm
|
||
|
||
```bash
|
||
npm i data-structure-typed --save
|
||
```
|
||
|
||
### yarn
|
||
|
||
```bash
|
||
yarn add data-structure-typed
|
||
```
|
||
|
||
```js
|
||
import {
|
||
Heap, Graph, Queue, Deque, PriorityQueue, BST, Trie, DoublyLinkedList,
|
||
AVLTree, SinglyLinkedList, DirectedGraph, RedBlackTree, TreeMultiMap,
|
||
DirectedVertex, Stack, AVLTreeNode
|
||
} from 'data-structure-typed';
|
||
```
|
||
|
||
If you only want to use a specific data structure independently, you can install it separately, for example, by running
|
||
|
||
```bash
|
||
npm i heap-typed --save
|
||
```
|
||
|
||
## Why
|
||
|
||
Do you envy C++ with [STL]() (std::), Python with [collections](), and Java with [java.util]() ? Well, no need to envy
|
||
anymore! JavaScript and TypeScript now have [data-structure-typed]().**`Benchmark`** compared with C++ STL.
|
||
**`API standards`** aligned with ES6 and Java. **`Usability`** is comparable to Python

You want to find a bunny named Pablo, and you have to start searching from the first bunny. If it's not Pablo, you continue following that bunny's tail to the next one. So, you might need to search n times to find Pablo (O(n) time complexity). If you want to insert a bunny named Remi between Pablo and Vicky, it's very simple. You just need to let Vicky release Pablo's tail, let Remi hold Pablo's tail, and then let Vicky hold Remi's tail (O(1) time complexity).</td>

However, if you don't know Pablo's number, you still need to search one by one (O(n) time complexity). Moreover, if you want to add a bunny named Vicky behind Pablo, you will need to renumber all the bunnies after Vicky (O(n) time complexity).</td>

For the tail of the line, we don't need to worry because each new bunny added to the tail is directly given a new number (O(1) time complexity) without needing to renumber all the previous bunnies.</td>

|
||
<td>A line of grouped, numbered bunnies with a sticky note on the first bunny. For this line, we manage it by groups. Each time we remove a bunny from the front of the line, we only move the sticky note to the next bunny. This way, we don't need to renumber all the bunnies behind the first bunny each time a bunny is removed. Only when all members of a group are removed do we reassign numbers and regroup. The tail is handled similarly. This is a strategy of delaying and batching operations to offset the drawbacks of the Array data structure that requires moving all elements behind when inserting or deleting elements in the middle.</td>

For example, if you directly come to the bunny Remi in the line and ask her where Vicky is, she will say the one holding my tail behind me, and if you ask her where Pablo is, she will say right in front.</td>

<td>Binary Search Tree (BST)</td>
|
||
<td>A tree-like rabbit colony composed of doubly linked lists where each rabbit has at most two tails. These rabbits are disciplined and obedient, arranged in their positions according to a certain order. The most important data structure in a binary tree (the core is that the time complexity for insertion, deletion, modification, and search is O(log n)). The data stored in a BST is structured and ordered, not in strict order like 1, 2, 3, 4, 5, but maintaining that all nodes in the left subtree are less than the node, and all nodes in the right subtree are greater than the node. This order provides O(log n) time complexity for insertion, deletion, modification, and search. Reducing O(n) to O(log n) is the most common algorithm complexity optimization in the computer field, an exponential improvement in efficiency. It's also the most efficient way to organize unordered data into ordered data (most sorting algorithms only maintain O(n log n)). Of course, the binary search trees we provide support organizing data in both ascending and descending order. Remember that basic BSTs do not have self-balancing capabilities, and if you sequentially add sorted data to this data structure, it will degrade into a list, thus losing the O(log n) capability. Of course, our addMany method is specially handled to prevent degradation. However, for practical applications, please use Red-black Tree or AVL Tree as much as possible, as they inherently have self-balancing functions.</td>

Each node is marked with a balance factor, representing the height difference between its left and right subtrees.

### Conciseness and uniformity
|
||
|
||
In [java.utils](), you need to memorize a table for all sequential data structures(Queue, Deque, LinkedList),
|
||
|
||
<table style="display: table; width:100%; table-layout: fixed;">
|
||
<thead>
|
||
<tr>
|
||
<th>Java ArrayList</th>
|
||
<th>Java Queue</th>
|
||
<th>Java ArrayDeque</th>
|
||
<th>Java LinkedList</th>
|
||
</tr>
|
||
</thead>
|
||
<tbody>
|
||
<tr>
|
||
<td>add</td>
|
||
<td>offer</td>
|
||
<td>push</td>
|
||
<td>push</td>
|
||
</tr>
|
||
<tr>
|
||
<td>remove</td>
|
||
<td>poll</td>
|
||
<td>removeLast</td>
|
||
<td>removeLast</td>
|
||
</tr>
|
||
<tr>
|
||
<td>remove</td>
|
||
<td>poll</td>
|
||
<td>removeFirst</td>
|
||
<td>removeFirst</td>
|
||
</tr>
|
||
<tr>
|
||
<td>add(0, element)</td>
|
||
<td>offerFirst</td>
|
||
<td>unshift</td>
|
||
<td>unshift</td>
|
||
</tr>
|
||
</tbody>
|
||
</table>
|
||
|
||
whereas in our [data-structure-typed](), you **only** need to remember four methods: `push`, `pop`, `shift`, and `unshift` for all sequential data structures(Queue, Deque, DoublyLinkedList, SinglyLinkedList and Array).
|
||
|

## Software Engineering Design Standards
|
||
|
||
We strictly adhere to computer science theory and software development standards. Our LinkedList is designed in the
|
||
traditional sense of the LinkedList data structure, and we refrain from substituting it with a Deque solely for the
|
||
purpose of showcasing performance test data. However, we have also implemented a Deque based on a dynamic array
|
||
concurrently.

## supported module system
|
||
|
||
Now you can use it in Node.js and browser environments
|
||
|
||
CommonJS:**`require export.modules =`**
|
||
|
||
ESModule: **`import export`**
|
||
|
||
Typescript: **`import export`**
|
||
|
||
UMD: **`var Deque = dataStructureTyped.Deque`**
|
