"Web22 de jul. de 2024 · Heap sort consists of two key steps, inserting an element and removing the root node. Both steps have the complexity O (log n). Since we repeat both steps n times, the overall sorting complexity is O (n log n). Note, that we didn't mention the cost of array reallocation, but since it's O (n), it doesn't affect the overall complexity. " - Heapsort step by step
