checks if the heap is valid (all nodes are positioned correctly) in log(n) runtime. // after sorting the heaps directly, node positions are mutated console.log(carsHeap.isValid()); // false console.log(numbersHeap.isValid()); // false console.log(bidsHeap.isValid()); // false fix...
If replaced element is greater than any of its child node in case of Min-HeapOR smaller than any if its child node in case of Max-Heap, swap the element with its smallest child(Min-Heap) or with its greatest child(Max-Heap). Keep repeating the above step, if ...
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 most important task has the lowest priority valu...

To build the project, run: ./gradlew ToDo Compare Keapsort to Quicksort. Looks like a tree-backed version of keap could be exposed as an immutable/persistent/lock-free heap data structure. In addition, it could support heap merge operation in Θ(1) time....
partition used by the heap. By default, a heap has a single partition. When a heap has multiple partitions, each partition has a heap structure that contains the data for that specific partition. For example, if a heap has four partitions, there are four heap structures; one in each ...
This global lock is used for protecting the heap data structure for multithreaded usage. Unfortunately, in high-traffic scenarios, a heap can still get bogged down in this global lock, leading to high contention and poor performance. On Windows 2000, the critical region of code inside locks is...
