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