Installation

Usage

You can import MinHeap and/or MaxHeap:

import { MinHeap, MaxHeap } from 'min-max-heap';

After that, you can initialise a heap and use the add, peek and pop commands to manage its state:

// Initialise heap
const heap = new MinHeap();

// Add new value to the heap
heap.add(1);                
heap.add(2);

// Get root value of the heap without removing it
heap.peek() // 2
heap.peek() // 2

// Get root value of the heap and remove it
heap.pop()  // 2
heap.pop()  // 1

Examples

MinHeap example:

import { MinHeap } from 'min-max-heap';

const heap = new MinHeap();

heap.add(1);
heap.add(2);
heap.add(3);
heap.add(4);
heap.add(5);

heap.peek() // 5
heap.pop()  // 5
heap.pop()  // 4
heap.peek() // 3
heap.pop()  // 3

MaxHeap example:

import { MaxHeap } from 'min-max-heap';

const heap = new MinHeap();

heap.add(1);
heap.add(2);
heap.add(3);
heap.add(4);
heap.add(5);

heap.peek() // 1
heap.pop()  // 1
heap.pop()  // 2
heap.peek() // 3
heap.pop()  // 3
