Application of Heap Data Structure:
- Heap is used to construct a priority queue.
- Heap sort is one of the fastest sorting algorithms with time complexity of O (N* log (N), and it’s easy to implement.
- Best First Search (BFS) is an informed search, where unlike the queue in Breadth-First Search, this technique is implemented using a priority queue.

Why do we need heap memory?
The advantages of heap memory are: Lifetime. Because the programmer now controls exactly when memory is allocated, it is possible to build a data structure in memory, and return that data structure to the caller. This was never possible with local memory, which was automatically deallocated when the function exited.
What is stored in heap?
Heap space is used for the dynamic memory allocation of Java objects and JRE classes at runtime. New objects are always created in heap space, and the references to these objects are stored in stack memory. These objects have global access and we can access them from anywhere in the application.
Which is better stack or heap?
Stack memory allocation is considered safer as compared to heap memory allocation because the data stored can only be access by owner thread. Memory allocation and de-allocation is faster as compared to Heap-memory allocation. Stack-memory has less storage space as compared to Heap-memory.

The basic concept of heap sort is to eliminate the elements one by one fr...

Working of Heap Sort
- In heap sort, there are two phases for sorting the elements. They are as follows: 1. In the first step, we’ll create a heap by adjusting the elements of the array. 2. After creating the heap, remove the root element repeatedly by swapping it with the last element of the array. Generally, Heap data structures are taught with heap sort. Basically, the Heap sort algorithm has a limited number of …
