Like a binomial heap, a fibonacci heap is a collection of tree. But in fibonacci heaps, trees are not necessarily a binomial tree. Also they are rooted, but not ordered.

If neither decrease-key not delete is ever invoked on a fibonacci heap each tree in the heap is like a binomial heap.

Fibonacci heaps have more relaxed structure than binomial heaps.

What will be the difference in running time of the heap sort algorithm if you start to apply heap sort with an array elements rather than max heap elements?

The heap sort algorithm is as follows: 1. Call the build_max_heap() function. 2. Swap the first and last elements of the max heap. 3. Reduce the heap by one element (elements that follow the heap are in sorted order). 4. Call the sift_down() function. 5. Goto step 2 unless the heap has one element. The build_max_heap() function creates the max heap and takes linear time, O(n). The sift_down() function moves the first element in the heap into its correct index, thus restoring the max heap property. This takes O(log(n)) and is called n times, so takes O(n * log(n)). The complete algorithm therefore equates to O(n + n * log(n)). If you start with a max heap rather than an unsorted array, there will be no difference in the runtime because the build_max_heap() function will still take O(n) time to complete. However, the mere fact you are starting with a max heap means you must have built that heap prior to calling the heap sort algorithm, so you've actually increased the overall runtime by an extra O(n), thus taking O(2n * log(n)) in total.


What are stored in heap memory?

Objects are stored in heap.


Difference between binary search tree and heap tree?

A binary search tree uses the definition: that for every node,the node to the left of it has a less value(key) and the node to the right of it has a greater value(key).Where as the heap,being an implementation of a binary tree uses the following definition:If A and B are nodes, where B is the child node of A,then the value(key) of A must be larger than or equal to the value(key) of B.That is,key(A) ≥ key(B).


In Java where do instance variables stored in memory?

An instance variable is part of an object. Therefore, it gets stored together with the object, on the heap. The heap is the part of memory which is used to store objects.An instance variable is part of an object. Therefore, it gets stored together with the object, on the heap.

How can the priority queue decrease-key operation be efficiently implemented to optimize the performance of the data structure?

To efficiently implement the decrease-key operation in a priority queue, you can use a data structure like a binary heap or Fibonacci heap. These data structures allow for efficient updates to the priority queue while maintaining the heap property, which helps optimize performance.


What are the key differences between a heap and a binary search tree (BST)?

A heap is a complete binary tree where each node has a value greater than or equal to its children (max heap) or less than or equal to its children (min heap). A binary search tree is a binary tree where the left child of a node has a value less than the node and the right child has a value greater than the node. The key difference is that a heap does not have a specific order between parent and child nodes, while a binary search tree maintains a specific order for efficient searching.


What is the difference between the stack and the heap?

The stack is a local memory reserve where the program stores variable and function data. The heap is a special memory reserve where the programmer can dynamically allocate memory from. The heap is useful when the programmer doesn't know how large to make certain variables, he just constructs one of the right size during run-time.


How can the priority queue decrease key operation be efficiently implemented?

The priority queue decrease key operation can be efficiently implemented by using a data structure like a binary heap or a Fibonacci heap. These data structures allow for the key of a specific element in the priority queue to be decreased in logarithmic time complexity, making the operation efficient.
