ds-js-stl

Install

npm install ds-js-stl

Description

The Library provides ready to use famous data structures to JavaScript. It draws inspiration from the structured beauty of C++ STL.

• Stack
• Queue
• Deque
• LinkedList
• DoubleLinkedList
• PriorityQueue

Usage

import { Stack, Queue, PriorityQueue, DoubleLinkedList, LinkedList, Deque } from 'ds-js-stl/index.js';

const stack = new Stack();
stack.push(32);
stack.pop();
console.log(stack.top());
console.log(stack.size());
console.log(stack.isEmpty());

const queue = new Queue();
queue.enqueue(32);
console.log(queue.dequeue());
console.log(queue.isEmpty());
console.log(queue.size());
console.log(queue.front());
console.log(queue.back());

const deque = new Deque();
deque.push_back(32);
deque.push_front(33);
console.log(deque.pop_front());
console.log(deque.pop_back());
console.log(deque.size());
console.log(deque.isEmpty());


const linkedList = new LinkedList();
linkedList.insert(32);
linkedList.display();
console.log(linkedList.size());
console.log(linkedList.isEmpty());
const headLinkedList = linkedList.head();


const doubleLinkedList = new DoubleLinkedList();
doubleLinkedList.insert(32);
doubleLinkedList.display();
console.log(doubleLinkedList.size());
console.log(doubleLinkedList.isEmpty());
const headLinkedList = doubleLinkedList.head();
const tailLinkedList = doubleLinkedList.tail();

// For MaxHeap
const priorityQueue = new PriorityQueue();
priorityQueue.insert(32);
console.log(priorityQueue.remove());
console.log(priorityQueue.peek());

//For MinHeap
const minPriorityQueue = new PriorityQueue("minHeap");
priorityQueue.insert(32);
console.log(priorityQueue.remove());
console.log(priorityQueue.peek());
