Average case
Enter no of elements :7
Enter the nos : 6
5

1
8
7
2
Heap array : 8 6 7 1 5 3 2
The sorted array is : 1 2 3 5 6 7 8
Complexity :
Best case = Avg case = Worst case = O(n logn)
Enter no of elements :7
Enter the nos : 12
10
8

2
Heap array : 12 10 8 9 7 4 2
The sorted array is : 2 4 7 8 9 10 12
Complexity :
Best case = Avg case = Worst case = O(n logn)
Enter no of elements :7
Enter the nos : 5
7

14
Heap array : 14 9 12 5 6 7 10
The sorted array is : 5 6 7 9 10 12 14
Complexity :
Best case = Avg case = Worst case = O(n logn)
Sort the Array Elements using Gnome Sort
