In Heapsort, we first build a heap, then we do following operations till the heap size becomes 1.
a) Swap the root with last element
b) Call heapify for root
c) reduce the heap size by 1.
In this question, it is given that heapify has been called few times and we see that last two elements in given array are the 2 maximum elements in array. So situation is clear, it is Max heapify which has been called 2 times.
