Input: The first line will consists of one integer T denoting the number of test cases. For each test case: 1) The first line consists of two integers N and K, N being the number of elements in the array and K denotes the number of steps of rotation. 2) The next line consists of N space separated integers, denoting the elements of the array A. Output: Print the required array. Constraints:
