What is a heap?
Answer:- A sorting algorithm that works by first organizing the data to be sorted into a special type of binary tree called a heap. The heap itself has, by definition, the largest value at the top of the tree, so the heap sort algorithm must also reverse the order. It does this with the following steps:1. Remove the topmost item (the largest) and replace it with the rightmost leaf. The topmost item is stored in an array.2. Re-establish the heap.3. Repeat steps 1 and 2 until there are no more items left in the heap.The sorted elements are now stored in an array.A heap sort is especially efficient for data that is already stored in a binary tree. In most cases, however, the quick sort algorithm is more efficient.GOURAV KHARE (CHANDIGARH)gouravsonu89@gmail.com
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 is heap -short?
The microprocessor architecture divides the memory into distinct areas. Heap is one of them. This is where you can statically/dynamically allocate memory.
Difference between Fibonacci heap and binomial heap?
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 is the runtime complexity of the heap sort algorithm?
The runtime complexity of the heap sort algorithm is O(n log n), where n is the number of elements in the input array.
What is the time complexity of heap sort algorithm?
The time complexity of the heap sort algorithm is O(n log n), where n is the number of elements in the input array.
What is the running time of heap sort algorithm in terms of time complexity?
The running time of the heap sort algorithm is O(n log n) in terms of time complexity.
What is the worst-case time complexity of the heap sort algorithm?
The worst-case time complexity of the heap sort algorithm is O(n log n), where n is the number of elements in the input array.
What is the runtime complexity of Dijkstra's algorithm?
The runtime complexity of Dijkstra's algorithm is O(V2) with a binary heap or O(E V log V) with a Fibonacci heap, where V is the number of vertices and E is the number of edges in the graph.
What is the best case scenario for the performance of heap sort algorithm?
The best case scenario for the performance of the heap sort algorithm is when the input data is already in a perfect heap structure, resulting in a time complexity of O(n log n).
What is the worst case scenario for the Heap Sort algorithm in terms of time complexity and how does it compare to other sorting algorithms?
The worst case scenario for the Heap Sort algorithm is O(n log n) time complexity, which means it can be slower than other sorting algorithms like Quick Sort or Merge Sort in certain situations. This is because Heap Sort requires more comparisons and swaps to rearrange the elements in the heap structure.

What is the time complexity of heap search in terms of its search time complexity?
The time complexity of heap search is O(log n), where n is the number of elements in the heap. This means that the search time complexity of a heap search operation is logarithmic in the number of elements in the heap.
What is the runtime complexity of Prim's algorithm for finding the minimum spanning tree of a graph?
The runtime complexity of Prim's algorithm for finding the minimum spanning tree of a graph is O(V2) using an adjacency matrix or O(E log V) using a binary heap.
What is the time complexity of removing an element from a heap data structure?
The time complexity of removing an element from a heap data structure is O(log n), where n is the number of elements in the heap.
What is the running time of heap sort algorithm?
The running time of the heap sort algorithm is O(n log n), where n is the number of elements in the input array.
