Heap sort is stable or unstable

WebStability in sorting means whether a sort algorithm maintains the relative order of the equals keys of the original input in the result output. So a sorting algorithm is said to be stable if two objects with equal keys appear in the same order in sorted output as they appear in the input unsorted array. Consider a list of pairs: WebHence, the former is a Stable sorting algorithm whereas the latter is an unstable sorting algorithm. Examples of stable sorting algorithm: Bubble sort, Insertion sort, Merge sort,...
