HEAPSORT( array A, int n) 1 BUILD-HEAP(A, n) 2 m n 3 while (m 2) 4 do SWAP(A[1],A[m]) 5 m m 1 6 HEAPIFY(A, 1,m) Considering the pseudo code of Heap

HEAPSORT( array A, int n)
1 BUILD-HEAP(A, n)
2 m n
3 while (m  2)
4 do SWAP(A[1],A[m])
5 m m− 1
6 HEAPIFY(A, 1,m)

Considering the pseudo code of Heap Sort discussed in lecture answer the following
questions (you need to justify your answers as well),
a. What will be the running time of Heap Sort if input is sorted in ascending
order
b. What will be the running time of Heap Sort if input is sorted in descending
order
c. What is best case input (format of input resulting in best case time) for Heap
Sort.
