The Selection sort algorithm can sort the given elements in the list either in ascending order or descending order whereas the Bubble sort algorithm sorts the given elements in the list in ascending order and then the list is reversed to display the elements in the list in descending order. Th...

Unlike selection sort, heapsort does not waste time with a linear-time scan of the unsorted region; rather, heap sort maintains the unsorted region in aheap data structure to more quickly find the largest element in each step.[1] Although somewhatslower in practi...
Heapsort is anin-place algorithm, but it is not astable sort. 堆排序也是原地排序,不稳定 堆排序简史 Heapsort was invented byJ. W. J. Williamsin 1964.[2] This was also the birth of the heap, presented already by Williams as a useful data structure in its own right.[3]In the same y...

This section describes the Selection Sort algorithm - A simple and slow sorting algorithm that repeatedly selects the lowest or highest element from the un-sorted section and moves it to the end of the sorted section.
