Many sorting algorithms came into development over the years, and Heap Sort is one of them. In the following article, we will explore the heap sort – How the algorithm works, its complexities, and how to implement it in JavaScript.What is sorting?Sorting is a technique used for ordering t...

Heap Sort is a popular and efficient sorting algorithm in computer programming. Learning how to write the heap sort algorithm requires knowledge of two types of data structures - arrays and trees. In this tutorial, you will understand the working of heap
For Sorting Large Arrays: Use Quick Sort or Merge Sort instead of Heap Sort. 10 Scenarios Where Heaps Are Used in Competitive Programming Finding the k-th Smallest or k-th Largest Element Merging k Sorted Arrays Implementing a Priority Queue Dijkstra’s Algorithm (Shortest Path in a Graph) Pr...
ALGORITHM # heapify for i = n/2:1, sink(a,i,n) → invariant: a[1,n] in heap order # sortdown for i = 1:n, swap a[1,n-i+1] sink(a,1,n-i) → invariant: a[n-i+1,n] in final position end # sink from i in a[1..n] function sink(a,i,n): # {lc,rc,mc} =...

Sorting Algorithm Quick reference Complexity Worst case time O(nlgn)O(nlgn) Best case time O(n)O(n) Average case time O(nlgn)O(nlgn) Space O(1)O(1) Strengths: Fast. Heap sort runs in O(nlg(n))O(nlg(n)) time, which scales well as nn grows. Unlike quicksort,...
So now we are going to begin a proper, step by step demonstration of the Heap Sort Algorithm in Python. Remember the workings of the heap that I mentioned earlier. Building the Initial Heap This array of 8 numbers is what we will be sorting with the Heap Sort Algorithm. ...
The algorithm works the same way but compares strings instead of numbers. Descending Order SortingTo sort in descending order, we modify the heapify function to create a min heap instead of a max heap: heap_sort_descending.php <?php function heapSortDescending(array &$arr): void { $n = ...
