My Professor gave me an assignment to make a code of a min heap but i can't use arrays to do it. And i've been having a lot of trouble finding a way to actually make one without it. Any ideas of how could i do it just using nodes, recursion or something else?
JavaScript does not have a built-in heap implementation, but we can efficiently implement Min Heap and Max Heap using an array and a comparator function. In this blog, we will cover: What is a Heap? Min Heap & Max Heap with Implementation in JavaScript (Node.js). Advantages & Disadvantage...
最大堆max-heap:每个节点的键值(key)都大于或等于其子节点键值 最小堆min-heap:每个节点的键值(key)都小于或等于其子节点键值 完全二叉树整棵树内没有任何节点漏洞,这带来一个好处:我们可以利用array来存储所有节点。假设我们动用一个小技巧,将array的#0元素保留(或设为无限大值或无限小值),那么完全二叉树中的...
heapify() :This will be the private method for the MinHeap class . The method ensures that heap property is maintained . insert() :The method is used to insert new nodes in the min heap . A new node is inserted at the end of the heap array , and we keep on swapping this node wi...

Also, in the min-heap, the value of the root node is the smallest among all the other nodes of the tree. Therefore, if “a” has a child node “b” then: Key(a) < key(b) represents the Min Heap Property. Let us display the max heap using an array. Therefore, the root node...

Our task is to convert that given min heap to max heap in O(n) time complexity. Example Live Demo #include<bits/stdc++.h> using namespace std; //converting a given subtree into a heap void convert_arrayheap(int arr[], int i, int n){ int l = 2*i + 1; int r = 2*i + 2...
Build a Min Heap given an array of numbers Instead of using insertNode() function n times for total complexity of O(nlogn), we can use the buildMinHeap() function to build the heap in O(n) time */ voidbuildMinHeap(minHeap *hp,int*arr,intsize) { ...
