     \caption{The operation of $\proc{Max-Heapify}(A,3)$ on the array $A=\langle$27, 17, 3, 16, 13, 10, 1, 5, 7, 12, 4, 8, 9, 0$\rangle$, where $\attrib{A}{heap-size}=14$.\,
     \textbf{(a)}\, The element $A[3]$ at node $i=3$ violates the max-heap property, since it is not larger than its left child $A[6]$.
     \textbf{(b)}\, After exchanging $A[3]$ with $A[6]$ the max-heap property is restored for node 3, but is destroyed for node 6, because now $A[6]$ is not larger than both children.
     In the recursive call $\proc{Max-Heapify}(A,6)$ the elements $A[6]$ and $A[13]$ are swapped, as shown in \textbf{(c)}.
-    The next recursive call $\proc{Max-Heapify}(A,13)$ just returns without making any further changes to the heap.} \label{fig:6.1-2}
