WebHeap sort, as the name suggests, makes use of heap data structure to sort the given array. It is one of the most preferred sorting algorithms due to its favorable worst-case time complexity. Similar to selection sort, heap sort also divides the given array into two regions –. Sorted region – built on the right side of the list/array. WebHeapsort is a comparison-based sorting algorithm that relies on maintaining a max-heap to quickly find the largest value on each iteration.
