ANDROUND - AND Rounds

You are given a cyclic array A having N numbers. In an AND round, each element of the array A is replaced by the bitwise AND of itself, the previous element, and the next element in the array. All operations take place simultaneously. Can you calculate A after K such AND 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 separated integers N (3 <= N <= 20000) and K (1 <= K <= 1000000000). The next line contains N space separated 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 separated list of N integers, specifying the contents of array A after K AND rounds.

Example

Sample Input:
2 
3 1 
1 2 3 
5 100 
1 11 111 1111 11111 
 
Sample Output:
0 0 0 
1 1 1 1 1

Implemented seg tree in one go with the actual logic. Segtree part is easy, try to prove to logic.

Segment Tree rocks!!

Accepted in one go, simple seg tree

If solving with segment tree just take care what value you return if that segment does not lie in the range :D
