WebHeap-Sort . Sorting Strategy: 1. Build Max Heap from unordered array; 2. Find maximum element A[1]; 3. Swap elements A[n] and A[1]: now max element is at the end of the array! 4. Discard node n from heap (by decrementing heap-size variable) 5. New root may violate max heap property, but its children are max heaps. Run max_heapify to fix this. 21 Web10 de ene. de 2024 · A Max-Heap is a complete binary tree in which the value in each internal node is greater than or equal to the values in the children of that node.
