WebThis property implies that heapSort's best-case is when all elements are equal (Θ(n), since you don't have to reheapify after every removal, which takes log(n) time since the max height of the heap is log(n)). It's kind of a lousy/impractical case, though, which is why the real best case for heapsort is Θ(n log n). Heapsort primarily competes with quicksort, another very efficient general purpose in-place comparison-based sort algorithm. Heapsort's primary advantages are its simple, non-recursive code, minimal auxiliary storage requirement, and reliably good performance: its best and worst cases are within a small constant factor of each other, and of the theoretical lower bound on comparison sorts.
