Input Format:

The first line contains an integer N representing the size of the array.

The second line contains N space-separated integers representing the elements of the array.

The last line contains an integer K representing the number of times the array has to be rotated in the left direction.

Output Format:

The only line of the output prints N space-separated integers representing the Rotated array elements.
