Heapsort is a comparison-based sorting algorithm, and is part of the selection sort family. Although somewhat slower in practice on most machines than a good
implementation of quicksort, it has the advantage of a worst-case O(n log n) runtime. Heapsort is an in-place algorithm, but is not a stable sort.

Worst case means that the array is already sorted in reverse order from the required. Worst Case Function just loop from max to min to create a sorted array in descending order

Quicksort in action on a list of random numbers. The horizontal lines are pivot values.Quicksort is a well-known sorting algorithm developed by C. A. R. Hoare
that, on average, makes (big O notation) comparisons to sort n items.

In computer science, merge sort or mergesort is an O(n log n) comparison-based
sorting algorithm. It is stable, meaning that it preserves the input order of equal elements in the sorted output. It is an example of the divide and conquer algorithmic paradigm.
It was invented by John von Neumann in 1945.

Bubble sort is a simple sorting algorithm. It works by repeatedly stepping through the list to be sorted, comparing two items at a time and swapping them if they are in the wrong order.
