priority Queue就是用Heap实现的。 classmaxHeap{constructor(){this.data=[null];}swap(i,j){consttmpNode=this.data[i];this.data[i]=this.data[j];this.data[j]=tmpNode;}addNode(node){this.data.push(node);if(this.data.length===2){return;}else{this.bubbleUp(this.data.length-1);}}remo...
JavaScript / Python-style iterator (recommended) Iterates over the heap consuming it, and guarantees to traverse the elements of the heap in the order of priority. Useful. const{Heap}=require('heap-js');// Get all tasks from the databaseconsttasks=db.collection.find().toArray();// The ...
Heap is a fundamental data structure that is widely used in competitive programming, especially in problems that require efficient retrieval of the smallest or largest elements in a dataset. ### JavaScript does not have a built-in heap implementation, but we can efficiently implement Min Heap and...
