Question

Which xxx completes the C heapsort() function?

a) SortHeap()
b) Heapify()
c) BuildHeap()
d) HeapSort()

Answer 1

The correct answer to which function completes the C heapsort() function is b) Heapify(). This function is essential in maintaining the heap properties during the sorting process after each extraction of the maximum element.

Step-by-step explanation:

The question asks which function completes the C heapsort() function. In the context of a heapsort algorithm in C programming, the correct answer is b) Heapify(). The heapsort algorithm typically involves three main steps:

• Building a heap from the input data (BuildHeap()),
• Then repeatedly extracting the maximum element from the heap and maintaining the heap property (Heapify()),
• Finally, sorting the elements (SortHeap(), although this is not a standard function but part of the overall heapsort procedure).

Heapify() is particularly crucial because it is used throughout the sorting process to maintain the heap properties after each extraction of the maximum element. Without the Heapify() function, the heap cannot be maintained, and the sorting process cannot proceed correctly.
