WebThe average case time complexity of heap sort is O (n log n). Worst Case Complexity - It occurs when the array elements are required to be sorted in reverse order. That means suppose you have to sort the array elements in ascending order, but its elements are in descending order. The worst-case time complexity of heap sort is O (n log n). Webstd:: make_heap < cpp ‎ algorithm C++ Algorithm library Constructs a max heap in the range [first, last). The first version of the function uses operator< to compare the elements, the second uses the given comparison function comp .
