WebThe Heapsort algorithm mainly consists of two parts- converting the list into a heap and adding the max element from the heap to the end of the list, while maintaining the heap structure. For easy implementation, we use a max-heap structure, where the max value always exists at the root.

WebHeapsort is a comparison-based sorting algorithm. Heapsort can be thought of as an improved selection sort: like that algorithm, it divides its input into a sorted and an unsorted region, and it iteratively shrinks the unsorted region by extracting the largest element and moving that to the sorted region.
