namastey-min-heap

namastey-min-heap is a JavaScript package that implements the Min-Heap data structure. It provides essential methods for inserting, removing, and accessing elements while maintaining the heap property.

• insert(value): Inserts a new value into the heap while maintaining the heap property.
• extractMin(): Removes and returns the minimum value (the root) from the heap.
• heapifyUp(index): Ensures the heap property is maintained after an insertion.
• heapifyDown(index): Ensures the heap property is maintained after extraction.
• peek(): Returns the minimum value without removing it from the heap.
• size(): Returns the number of elements in the heap.
• isEmpty(): Returns true if the heap is empty, false otherwise.

To install the namastey-min-heap package globally, run the following command:

npm install -g namastey-min-heap

const MinHeap = require('namastey-min-heap');

const heap = new MinHeap();
heap.insert(10);
heap.insert(5);
heap.insert(30);
heap.insert(2);

console.log('Min element:', heap.peek()); // Output: Min element: 2
console.log('Extracted min:', heap.extractMin()); // Output: Extracted min: 2
console.log('Min element:', heap.peek()); // Output: Min element: 5
console.log('Heap size:', heap.size()); // Output: Heap size: 3
