###  All submissions for this problem are available. 

You are given a cyclic array A having N numbers. In an XOR round, each element of the array A is replaced by the bitwise XOR (Exclusive OR) of itself, the previous element, and the next element in the array. All operations take place simultaneously. Can you calculate A after K such XOR rounds ?

### Input

The first line contains the number of test cases T (T <= 50). There follow 2T lines, 2 per test case. The first line contains two space seperated integers N (3 <= N <= 500) and K (1 <= K <= 1000000000). The next line contains N space seperated integers Ai (0 <= Ai <= 1000000000), which are the initial values of the elements in array A.

### Output

Output T lines, one per test case. For each test case, output a space seperated list of N integers, specifying the contents of array A after K XOR rounds.
