This is the Java Program to Implement Heap Sort Using a Priority Queue. Problem Description Given an array of integers, sort the array using heap sort which uses a priority queue. A priority queue is a min-heap in which every node is smaller than its elements. Problem Solution Add all the elements of the array … Read more
This is a Java Program to Implement Meldable Heap. A randomized meldable heap (also Meldable Heap or Randomized Meldable Priority Queue) is a priority queue based data structure in which the underlying structure is also a heap-ordered binary tree. However, there are no restrictions on the shape of the underlying binary tree. Here is the … Read more
This Java program is to implement Min heap. A Heap data structure is a Tree based data structure that satisfies the HEAP Property “If A is a parent node of B then key(A) is ordered with respect to key(B) with the same ordering applying across the heap.” So in a Min Heap this property will … Read more
This Java program is to implement max heap. A Heap data structure is a Tree based data structure that satisfies the HEAP Property “If A is a parent node of B then key(A) is ordered with respect to key(B) with the same ordering applying across the heap.” So in a Min Heap this property will … Read more
This is a Java Program to implement Ternary Heap. Here Ternary Heap is implemented using concept of D-ary Heap. Here is the source code of the Java program to implement Ternary Heap. The Java program is successfully compiled and run on a Windows system. The program output is also shown below. /** * Java Program to … Read more
This is a Java Program to implement Skew Heap. A skew heap (or self-adjusting heap) is a heap data structure implemented as a binary tree. Skew heaps are advantageous because of their ability to merge more quickly than binary heaps. In contrast with binary heaps, there are no structural constraints, so there is no guarantee … Read more
This is a Java Program to implement Binomial Heap. A binomial heap is a heap similar to a binary heap but also supports quick merging of two heaps. This is achieved by using a special tree structure. It is important as an implementation of the mergeable heap abstract data type (also called meldable heap), which … Read more
This is a Java Program to implement D-ary Heap. A heap is a specialized tree-based data structure that satisfies the heap property: If A is a parent node of B then key(A) is ordered with respect to key(B) with the same ordering applying across the heap. Either the keys of parent nodes are always greater … Read more
This is a Java Program to implement Leftist Heap. A leftist heap is a priority queue implemented with a variant of a binary heap. Every node has an s-value which is the distance to the nearest leaf. In contrast to a binary heap, a leftist tree attempts to be very unbalanced. In addition to the … Read more
This is a Java Program to implement Fibonacci Heap. Fibonacci heap is a heap data structure consisting of a collection of trees. It has a better amortized running time than a binomial heap. The name of Fibonacci heap comes from Fibonacci numbers which are used in the running time analysis. Using Fibonacci heaps for priority … Read more
