Reverse array in groups
     

Given an array, reverse every sub-array formed by consecutive k elements.

Input:

The first line of input contains a single integer T denoting the number of test cases. Then T test cases follow. Each test case consist of two lines. The first line of each test case consists of an integer N, where N is the size of array.The second line of each test case contains N space separated integers denoting array elements.The third line of each test case consists of an integer K.

Output:
Corresponding to each test case, in a new line, print the modified array.

Constraints:

1 ≤ T ≤ 100
1 ≤ N ≤ 500
1 ≤ A[i] ≤ 500

Example:

Input
1
5
1 2 3 4 5
3

Output
