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).

Web17 de jun. de 2024 · This upper bound, though correct, is not asymptotically tight. We can derive a tighter bound by observing that the running time of Heapify depends on the height of the tree ‘h’ (which is equal to lg (n), where n is a number of nodes) and the heights of most sub-trees are small. The height ’h’ increases as we move upwards along the tree. aldi 22406Web25 de feb. de 2024 · Complejidad del algoritmo de ordenamiento por montículos Complejidad de tiempo.
